Abstract

The invention discloses a new energy vehicle powertrain spline reliability test system and a test method, wherein the test system includes a double dynamometer system, a motor controller, a battery simulator, an output control device, and a signal acquisition device. , the test method includes the following steps: powertrain installation, layout according to the above test system; test system debugging; preliminary spline reliability test; spline reliability test; spline reliability test retest; data analysis. The new energy vehicle powertrain spline reliability test system and test method provided by the present invention can make the powertrain spline reliability test not restricted by the road environment through the strengthened working conditions of the bench, and can make the powertrain in a long time Rapid acceleration and rapid deceleration state, thereby shortening the test period, which is conducive to the timely change of the scheme in the design process.

Description

technical field [0001] The invention belongs to the field of new energy vehicle power system testing, and relates to a test device and method of a power assembly bench, in particular to a new energy vehicle power assembly spline reliability testing method. Background technique [0002] In recent years, new energy vehicles have gradually entered the big stage of the automobile industry and shined brilliantly, and electric vehicles are the main force in new energy vehicles. Motor splines, transmission splines and engine splines are the main wear parts of new energy vehicles during driving, and play a vital role in the reliability of the vehicle. Therefore, the reliability test of the powertrain spline is very necessary. However, the traditional reliability road test takes several months. Using this method to verify or accept the design of the spline will take a long period, which is not conducive to design modification. [0003] Therefore, how to shorten the period of the sp...
