Problems solved by technology

[0003] Since the critical speed of instability of the actual vehicle is often very large, if the desired result is obtained through the actual vehicle experiment, it may bring irreparable losses to the experimental device and experimental equipment, and may cause very serious consequences
Therefore, real vehicle instability experiments are extremely rare

Description

technical field [0001] The invention relates to the field of vehicle ground dynamics experiments, in particular to a vehicle stability experiment device. Background technique [0002] With the increase of vehicle speed, the study of vehicle dynamics is extremely important. Vehicle instability will not only affect the ride comfort, but also may lead to serious consequences of vehicle crash. Therefore, vehicle stability, as one of the most basic indicators of vehicle dynamic performance, is the primary consideration of vehicle dynamics research. The critical speed of vehicle instability and the mechanism of instability are the main contents of vehicle stability research. The former determines the maximum allowable speed of the vehicle, and the latter plays an important guiding role in the control and prevention of instability. [0003] Because the destabilizing critical speed of the actual vehicle is often very large, if the desired result is obtained through the actual vehi...
