Abstract

The invention discloses a new energy automobile powertrain spline reliability test system and test method. The test system comprises a dual dynamometer system, a motor controller, a battery simulator,an output control device and a signal acquisition device. The test method comprises the following steps: powertrain installation: performing arrangement according to the above test system; test system commissioning; initial test of a spline reliability test; spline reliability test; spline reliability test retest; and data analysis. The new energy automobile powertrain spline reliability test system and test method provided by the invention can provide a powertrain spline reliability test not limited by a road environment through the strong chemical condition of the gantry, and cam make the power system in a rapid acceleration and rapid deceleration state for a long time so as to shorten the test cycle, and facilitates timely changes in schemes in a 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 for a power assembly bench, in particular to a new energy vehicle power assembly spline reliability testing system and 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 ...
