Addressing heavy equipment acoustic comfort with 3D simulation solutions

By Beth Warner

Every heavy equipment OEM wants their products to be perceived as the best on the market, and none of them wants a reputation for having uncomfortable or noisy machines. This puts pressure on these companies to not only meet the minimum standards of the market, but to exceed them. When it comes to cabin and acoustic comfort, exceeding those expectations requires a structured engineering approach that is designed to rapidly solve problems at the lowest cost. Thus, it becomes critical to identify noise and vibration sources early in the development process.

Siemens Simcenter can help manufacturers use advanced measurement systems and 3D mechanical and acoustic simulation software packages to meet these challenges. A hybrid approach that uses simulation alongside testing from the earliest stages and enables collaboration between simulation and testing processes during the development cycle can result in most NVH problems getting resolved before the prototype phase.

Below are several resources detailing how manufacturers are using 3D simulation and measurement system solutions to tackle the complex challenges of acoustic comfort within heavy equipment:
