摘要：

In order to review the development progress of the automobile inertial parameters measuring technique and improve measuring accuracy, the effect of inertial parameters on automobile system dynamics was analyzed first. Then both the approaches of inertial parameters estimation and measuring devices were studied. The experiments should be designed according to different automobile system dynamics models to estimate inertial parameters. The effects of input and output data accuracy on estimation results should be considered. The devices measuring automobile inertial parameters have developed from the single parameter measuring device to multiple parameters measuring device. The main principles include compound pendulum principle or force/motion principle. The device friction and the stiffness of support system were the two major factors affecting measuring accuracy. The system dynamics methods were used to establish the compensation model of the measuring devices friction and stiffness, and the effect on automobile inertial parameters measuring was analyzed. The result shows that it is necessary to adopt the lightweight design and error analysis technique to optimize the design of platform. The calculation methods proposed to examine the effect of devices friction and stiffness on automobile inertial parameters measuring can improve measuring accuracy.
