A comprehensive test bench for electric wheels based on dynamic and static vertical loading devices and real-time simulation

Abstract

An electric wheel comprehensive test bench based on a dynamic and static vertical loading device and real-time simulation includes a real-time data acquisition control platform and a test bench; the data real-time acquisition and control platform includes: a host computer, a target computer, and a model for the target computer CAN communication card of ADVANTECH PCI-1680U and a data acquisition card of ADVANTECH PCI-1712; the test bench includes: base, electric wheel, electric wheel controller, roller, dynamic and static vertical load loading device, rotating speed Torque sensor, coupling, dynamometer, dynamometer controller, V / F converter; the test bench can accurately simulate various loads on the wheels of electric wheeled electric vehicles during road driving, especially accurate The vertical load on the electric wheel is simulated, so as to provide a test environment close to the real vehicle for developing the electric wheel and testing its performance.

Description

technical field [0001] The invention relates to electric vehicle bench test technology, in particular to an electric wheel comprehensive test bench based on dynamic and static vertical loading devices and real-time simulation. Background technique [0002] The bench test is mostly used in the field of automobile and assembly development. In the early stage of automobile development, through the automobile bench test, it can simulate the starting, acceleration, climbing, braking and other working conditions of the car. If the accuracy can be close to the real car road test, It can improve the safety of vehicle and component experiments, reduce the dependence on the experimental site, reduce the cost of control system development, and effectively shorten the development cycle. [0003] As a new type of electric vehicle, the electric wheel electric vehicle improves the transmission efficiency of the whole vehicle and simplifies the chassis structure because of the cancellation ...

AI Technical Summary

Problems solved by technology

[0004] However, while the electric wheel electric vehicle brings the above advantages, it also brings the following problems: the unsprung mass of the whole vehicle changes greatly after the electric wheel is adopted, so the change of the vertical load of the wheel has a great impact on the whole vehicle of the electric wheel electric vehicle The performance has a great impact, and whether it can accurately simulate the change of the vertical load of the wheel during the driving process of the real vehicle has become the key to the development of the electric wheel test bench
