Comprehensive electric wheel test platform based on dynamic and static vertical loading device and real-time simulation

Abstract

The invention relates to a comprehensive electric wheel test platform based on a dynamic and static vertical loading device and real-time simulation. The comprehensive electric wheel test platform based on the dynamic and static vertical loading device and real-time simulation comprises a real-time data acquisition control platform and a test bed; the real-time data acquisition control platform comprises an upper computer, a target machine, a CAN communication card and a data acquisition card; the CAN communication card is used for the target machine; the type of the CAN communication card isADVANTECH PCI-1680U; the type of the data acquisition card is ADVANTECH PCI-1712; and the test bed comprises a base, an electric wheel, an electric wheel controller, a roller, a dynamic and static vertical loading device, a speed torque sensor, a coupler, a dynamometer, a dynamometer controller and a V / F converter. The test platform can accurately simulate all kinds of loads subjected by an electric wheel type electric car wheel in a road driving process, and particularly can accurately simulate vertical load subjected by the electric wheel; and thus, a test environment close to a real train can be provided for developing the electric wheel and testing the performance of the electric wheel.

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 ...

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
