Description

technical field [0001] The invention relates to a vehicle dynamics test stand, in particular to a multifunctional vehicle dynamics test stand with a loading device. Background technique [0002] Vehicle dynamics mainly includes longitudinal dynamics, lateral dynamics and vertical dynamics. At present, the methods used in vehicle dynamics testing and research mainly include real vehicle road test, computer simulation and bench test. The real vehicle road test requires a large test site, and the test cost is high. The computer simulation method needs to establish a mathematical model of the vehicle and its components, and requires experimental verification. The bench test method overcomes the shortcomings of the real vehicle road test and computer simulation method to a large extent, and has been widely used in vehicle dynamics testing and research. However, the current vehicle dynamics test bench uses longitudinal dynamics, lateral dynamics Or the testing and research of v...
