Industrial trends<\/strong><\/h2>\n\n\n\n
Automotive manufacturers are in a growing need to improve efficiency in their vehicle development process. This new challenge is a consequence of trends in the automotive industry, such as electrification, virtual sensors, new mobility needs, and other increased complexity.<\/p>\n\n\n\n
Vehicle development teams need to execute performance evaluations on their new products to fulfill the expectation derived from the market. Traditionally, all performance evaluations were done through physical testing; today, it\u2019s almost impossible to do this for every single design variant. The need for a virtual validation of the vehicle performance is increasing. <\/p>\n\n\n\n
But this doesn\u2019t mean that the need for physical testing is decreasing. Simulation models and simulated data still need to be correlated with real-life measurements to achieve realistic results. This approach shift from test-centric development to model-based development (MBD) provides better engineering insight by tightly integrating and balancing test and simulation to increase productivity in vehicle development.<\/p>\n\n\n\n
Impacts to vehicle development teams<\/strong><\/h2>\n\n\n\n
As explained above, the need for virtual validation is increasing. However, simulation engineers also need to validate their models by tuning model parameters and apply physical vehicle loads to their simulation model to increase realism. In the meantime, test engineers need to provide accurate measurements and be sure that they acquired physical data from all critical locations all around the vehicle.<\/p>\n\n\n\n
It is also important to indicate that these two worlds are historically isolated from each other and exchanging data between them can be difficult. Important information might easily be lost when converting from one environment to the other. <\/p>\n\n\n\n
Simcenter Model-based System Testing (MBST)<\/a> is specifically aimed to bring simulation and testing into a single environment.<\/p>\n\n\n\n
