One of the methods of studying the dynamic properties of a vehicle is to conduct tests using a real object. In many cases, it is impossible to perform such an experiment on a vehicle, either for technological reasons or due to the cost of the experiment. An alternative to testing on a real object is numerical testing. The models used for computer simulation contain a number of simplifications that have a decisive impact on the quality of the results obtained. To minimize the number of these simplifications, our Institute offers research in the development of data for modeling vehicle dynamics.
