Title Dynamics modeling and simulation of vehicle robot driver
Abstract The industry of vehicle manufacturing has been highly prosperous in our country nowadays because of the development of the science and technology ，also the increasing demand of people. While residents plan to buy cars, the performance is a significant point to affect their choice. Consumers will fit their eyes on the feeling of driving, the comfort, the appearance, especially on safety. For these reasons, we need to do a large amount of experiments on the vehicles. The invention of vehicle robot driver could reduce the burdens of the test persons, and robot drivers have the advantages such as high repeat qualities, high precisions, and the convenience of measurement and control. This article finished the total design of the vehicle robot driver by learning the relevant data. Also the 3D modeling of the mechanism design will be showed to be done by using the software CATIA. After finishing the mechanism design, the dynamics simulation has been done on the software ADAMS to verify the feasibility of the mechanism. We do the flexible treatment on the rigid multi-body system after the former simulation and do the simulation on the flexible multi-body as well. On one hand, the simulations analysis the dynamic characteristics of the actuators during the test, on the other hand ensure the accuracy of the mechanism movement.
