The invention provides a whole vehicle moment of inertia measuring system. The whole vehicle moment of inertia measuring system comprises a base; an actuator, which is disposed on the base; a carrying platform; a clamp assembly, which is respectively connected with a chassis of a to-be measured vehicle and the carrying platform, and is used to connect the to-be-measured vehicle and the carrying platform rigidly; a plurality of sensors, which are disposed between the chassis of the to-be-measured vehicle and the carrying platform, and is used to detect the action force of the to-be-measured vehicle applied to the carrying platform; a wheel restraining assembly, which is used for fixing the wheels of the to-be-measured vehicle; and a control unit, which is respectively connected with the actuator assembly and a plurality of sensors in a controlled way. The to-be-measured vehicle is disposed on the carrying platform, and the actuator is used to carry and drive the carrying platform. The whole vehicle moment of inertia measuring system is advantageous in that use is safe, and requirements on universality and convenience of measuring moment of inertia of different vehicles are satisfied. The whole vehicle moment of inertia measuring system is directly used for measuring a whole vehicle, and therefore deviation generated by indirect measurement is prevented, precision of measuring results is improved, and measuring efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a measurement system for the moment of inertia of a complete vehicle. Background technique [0002] In the process of automobile research and development, performance development engineers often use the moment of inertia of the entire vehicle to perform dynamic simulation of the model, and formulate improvement plans based on the simulation results to improve the driving performance of the vehicle. Therefore, obtaining accurate vehicle moment of inertia data is an important test item in the vehicle testing work. [0003] At present, the moment of inertia test of the whole vehicle is mainly carried out on the moment of inertia test bench of the whole vehicle. The driving mechanism of the test bench drives the body to continuously rotate in the three axes of pitch, roll and yaw, and the mechanical sensor records the load during the movement. Changes, and then calc...
