Abstract
The invention discloses a multifunctional vehicle dynamics dynamical characteristic test bed with a loading device, comprising a rotary encoder, a torque motor, a longitudinal guide rail, a horizontal guide rail, a rotating disc, an outer rotor motor, a force sensor and a torque sensor, a rotary drum, a tyre flange, a horizontal loading hydraulic cylinder with the force sensor, a horizontal loading matching hydraulic cylinder with the force sensor, a vertical loading hydraulic cylinder with the force sensor, an angle sensor, a loading bracket, a rotating speed sensor, a centering roller lifter, a centering roller, a motor, a measurement and control system, and the like. The invention can be used for exerting longitudinal force and vertical force on vehicle wheels and loading horizontal force and aligning resistance torque at the same time, simulating the turning driving of a vehicle by turning the vehicle wheels with the rotary drum together, measuring the turning angles of the vehicle wheels, better simulating the actual driving work conditions of the vehicle and realizing the comprehensive research of integral vehicle dynamics, and provides the vehicle dynamics test bed which has better performance.
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...
