Title:
METHOD FOR COMPILING LOAD SPECTRUM OF RELIABILITY TEST FOR HIGH-SPEED BEARING OF ELECTRIC DRIVE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/028419
Kind Code:
A1
Abstract:
A method for compiling a load spectrum of a reliability test for a high-speed bearing of an electric drive system. On the basis of load data of the full life cycle of an electric drive system, same is associated with a high-speed bearing failure dominant load, and action frequencies of load classes are counted by using a multi-dimensional load joint counting method; a mechanical equilibrium equation for a bearing is constructed; a load class of a reliability test is determined by means of the damage contribution distribution of different load classes and a cumulative damage contribution distribution; the time of the load class of the reliability test is determined according to the principles of overall frequency consistency and damage consistency; and in view of an extreme load working condition, a load spectrum of the reliability test for a high-speed bearing is finally constructed. The constructed load spectrum of the reliability test is associated with an actual failure mode, such that the reliability level of a high-speed bearing can be effectively verified, and the time for the reliability test is shortened, thereby providing support for the high-quality development of the high-speed bearing.
