Siemens PLM Software solutions help Ural Locomotives launch Russia\u2019s first modern high-speed electric train in less than three years.<\/h2>\n\n\n\n

High-speed trains shorten the travel time between the regions of a large country such as Russia,and offer excellent riding comfort. The first such train assembled in Russia was the Lastochka (the E\u04212G make). It can go 160 kilometers per hour (km\/h), and the standard five-carriage train can carry up to 1,500 passengers. The Lastochka, which means \u201cswallow bird\u201d in Russian, has been modified to better match the country\u2019s conditions: The electric train can run in a tropical climate and in a frigid northern climate. The acceptable tempera\u00adture range is from -40 to +40 Celsius. The carriage door arrangements are suitable for Russian railway platforms that can be installed at various heights.<\/p>\n\n\n\n

The Lastochka development began in 2009 when Russian Railways ordered a regional dual-mode electric train from Siemens. The train had to be adapted to Russian condi\u00adtions. The new trains were intended for Sochi commuter service during the 2014 Winter Olympics. Then they would serve other routes to provide direct links on tracks with both DC and AC power.<\/p>\n\n\n\n

The new Russian train design was based on the Siemens Desiro ML five-carriage electric train. The first 54 EC1 series trains were manufactured by Siemens in Krefeld Germany between 2011 and 2014.<\/p>\n\n\n\n

To enable domestic production of the high-speed trains in Russia, in 2010 Siemens AG and Sinara Group established a joint venture called Ural Locomotives, LLC. Today the company manufactures DC (model 2EC6) and AC (model 2EC7) elec\u00adtric freight locomotives and DC mainline electric locomotives (model 2EC10).<\/p>\n\n\n\n

\u201cUral Locomotives was under significant time pressure to not just assemble the electric train in Russia following the origi\u00adnal German drawings, but to develop a complete design package that complied with Russian standards for the product assembly with components from Russian suppliers,\u201d says Vitaly Brexon, deputy chief executive officer (DCEO) for engineering policy, Ural Locomotives. \u201cThe local content had to be really high, so we needed the original 3D models.\u201d<\/p>\n\n\n\n

A track to digitalization  <\/h2>\n\n\n\n

After an in-depth analysis, Ural Locomotives decided to deploy Siemens PLM Software solutions to produce the Lastochka for several reasons: First, it would facilitate the use of a high level of local content; second, Siemens\u2019 software is compliant with the Russian unified system for design documentation (ESKD) engineer\u00ading standards; third, Siemens PLM Software has a highly capable product lifecycle management (PLM) deployment team in Russia, and fourth, Ural Locomotives determined that Siemens\u2019 products offer the most advanced digitalization solutions. This includes systems-driven product development, cost and value engineering, digital engineering analysis and product requirements validation technologies.<\/p>\n\n\n\n

A well-coordinated Siemens PLM Software technology deployment led to rapid end-to-end digitalization. It took less than three years to launch an industrial grade produc\u00adtion of the Lastochka trains. The local content of the product is as high as 80 percent.<\/p>\n\n\n\n

\u201cSiemens PLM Software\u2019s technologies help us to rapidly develop modern rolling stock, and enables us to be up-to-date so we can compete with famous companies both domestically and internationally,\u201d says Peter Vaulin, head of the mechanical design division in the research and devel\u00adopment (R&D) department of Ural Locomotives.<\/p>\n\n\n\n

The digitalization began with the deploy\u00adment of Teamcenter\u00ae software for product data management (PDM) and NX\u2122 soft\u00adware for computer-aided design (CAD). Concurrently the designers received CAD training to enable them to design the Lastochka train based on the DESIRO RUS platform.<\/p>\n\n\n\n

Ural Locomotives took a comprehensive approach to information technology (IT)<\/h2>\n\n\n\n

The corpo\u00adrate enterprise resource planning (ERP) management system and Teamcenter integration project included transferring digital product structures and changes. The integration has been implemented with built-in Teamcenter tools. It has enabled Ural Locomotives to establish a unified information environment for all of its divisions. It has also improved the performance and coordination of the manufacturing and auxiliary departments.<\/p>\n\n\n\n

Introducing Siemens PLM Software into the design process has resulted in a unified approach to managing design documents, product structure, references and document storage. Now the design documents are reviewed and approved digitally across the departments. The designers develop 3D models while 2D drawings and bill-of-materials (BOMs) are generated automatically. They handle large assemblies, perform engineering analysis and computer numerical control (CNC) code generation using 3D part models.<\/p>\n\n\n\n

Using concurrent engineering in NX that is managed in Teamcenter has helped the firm design the complicated components of the Lastochka electric train and its modifications in an efficient and high-quality way, removing errors in design documents and establishing an automated compliance check procedure.<\/p>\n\n\n\n

\u201cWorking with Teamcenter, the designers concurrently develop all the components in a single model and can see any updates made by other stakeholder,\u201d says Dmitry Khaziyev, senior design engineer, locomo\u00adtive underframe department, mechanical design division. \u201cSuch an approach reduces errors that are hard to identify with other design procedures and would likely only be found once the product was assembled.\u201d<\/p>\n\n\n\n

Delivering accurate analysis<\/h2>\n\n\n\n

Due to the close partnership with Siemens PLM Software\u2019s Russian team, company experts have quickly mastered structural element strength, rigidity analysis and dynamic train performance analysis to estimate ride smoothness and the comfort of passengers. To meet the passive safety and crash worthiness requirements, colli\u00adsions with obstacles on the track have been virtually simulated.<\/p>\n\n\n\n

Siemens PLM Software\u2019s Simcenter\u2122 soft\u00adware is an engineering analysis tool that has enabled Ural Locomotives to create an efficient Lastochka train and locomotive design in a virtual environment without many physical tests.<\/p>\n\n\n\n

\u201cEngineering analysis systems like Simcenter significantly boost the perfor\u00admance of our engineers, analysts and designers, and reduce the scope of works for the test engineers,\u201d says Peter Vaulin, head of the mechanical design division, research and development (R&D) depart\u00adment of Ural Locomotives. \u201cIn the shortest time possible we try a large number of design options and evaluate each design virtually without building any prototypes. It saves a lot of time. Now we can develop modern rolling stock really fast, and be up-to-date. We compete with famous companies both domestically and internationally.\u201d<\/p>\n\n\n\n

With the digitalization approach used in the Siemens PLM Software\u2019s solutions today, Ural Locomotives fully complies with all the custom union standards, certification requirements and directives.<\/p>\n\n\n\n

Achieving safety and comfort<\/h2>\n\n\n\n

The Lastochka train design meets all the safety and ergonomics standards. The train body components are made of extruded aluminum. The metal is corro\u00adsion-resistant, while the special panel design ensures low weight and structural rigidity of the carriage required for a high-speed ride. The manufacturing of such body parts is quite innovative for Russian industry. It is similar to the aero\u00adspace industry, but Ural Locomotives is the only Russian company that manufactures highly complicated parts from long extruded profiles.<\/p>\n\n\n\n

The CNC machining of carriage body parts had to be planned from scratch. The initial task was to machine a carriage size panel 23.9 meters (m) long. The wall compo\u00adnents misaligned by two to three millimeters (mm) when fixed to the machine tool. Even worse, the side component length varied by three to four mm. The panel carries important interior components, electric equipment and heating systems. For this reason, it was important and difficult to align all the parts while preserving the panel flatness. The Siemens PLM Software experts and their colleagues from Ural Locomotives had to adapt the milling operation and correct the CNC code for each panel segment.<\/p>\n\n\n\n

Working with Teamcenter, the designers concurrently develop all the components in a single model and can see any updates made by other stakeholders. Such an approach reduces errors that are hard to identify with other design procedures and would likely only be found once the product was assembled. <\/p>Dmitry KhaziyevSenior Design Engineer, Locomotive Underframe Department, Mechanical Design DivisionUral Locomotives<\/cite><\/blockquote>\n\n\n\n

The panel was measured and the cloud point was processed with NX CAM<\/strong><\/a>. Then the module generated a CNC code perfectly adaptable for any surface irregu\u00adlarities. The adaptive machining technology available in N\u0425 \u0421AM takes into account any manufacturing environment changes occurring after the initial analysis.<\/p>\n\n\n\n

\u201cWithout adaptive milling with<\/em> NX CAM,<\/a> it would have been impossible to machine the extruded aluminum part<\/strong>s,\u201d says Vladimir Dudorov, manufacturing engineer, welding and assembly department, Train Production Planning Division, Ural Locomotives. \u201cWe would have faced consistent overcuts and faulty parts<\/strong><\/em>.\u201d<\/p>\n\n\n\n

Having achieved excellent results with the carriage side wall machining, the experts adapted the carriage roof and underframe machining in which the components also have varying length and other special features.<\/p>\n\n\n\n

Initially at Krefeld where the Desiro trains were manufactured, such parts were machined using expensive tooling. Now Ural Locomotives is able to use affordable tooling and the workpiece location proce\u00addure developed with NX CAM. A train part workpiece is installed on a machine that doesn\u2019t require a high degree of accuracy for its extrusion. NX CAM is used to gener\u00adate the CNC code and a CNC machine performs all the machining. NX CAM generates the CNC code.<\/p>\n\n\n\n

The Siemens PLM Software suite of solu\u00adtions has delivered high-quality manufacturing of the expensive Lastochka train components with lower production planning costs. Manufacturing defects have been eliminated. The solutions based in NX CAM have reduced machine setup time with automated workpiece location, while virtual CNC code simulation has accelerated the planning time by 30 percent. The manufacturing time for carriage workpieces was reduced by 40 percent.<\/p>\n\n\n\n

Lessons learned during the Lastochka project at Ural Locomotives have been applied to designing a mainline electric freight locomotive with an induction traction motor (model 2EC10), one of the most powerful DC electric engines for the 1,520 mm gauge lines. The electric loco\u00admotive can drive trains weighing over 9,000 tons. That is twice as much weight as the commonly used VL (a class of Australian diesel locomotives built by Avteq, Melbourne) locomotives.<\/p>\n\n\n\n

Leveraging digital technologies<\/h2>\n\n\n\n

In the near future the company is going to deploy the Teamcenter Requirements Management module to consolidate and apply the requirements to train design, safety, efficiency and noise, and to gener\u00adate new product configurations as these initial requirements change. The Teamcenter CAD Data Management module will also be deployed for effi\u00adciently coordinating engineering analysis data, easily searching and re-using analy\u00adsis results, and creating and managing complex assemblies.<\/p>\n\n\n\n

Siemens\u2019 advanced digital technologies have helped Ural Locomotives develop and follow the best global practices for railway engineering.<\/p>\n\n\n\n
