Method and device for predicting life of mechanical component of electric drive assembly

Abstract

The invention discloses a method and a device for predicting the life of a mechanical component of an electric drive assembly. By collecting historical data and current characteristic parameter data of the mechanical component of the electric drive assembly, the modeling of a screening model and a life prediction model is completed, whether the mechanical component is in a failed state is judged according to the characteristic parameter data and the screening model, if the mechanical component is in the failed state, alarm information is sent in time to remind the staff to repair and replace the mechanical component, if the mechanical component is in a non-failed state, the remaining life of the mechanical component is accurately predicted via the life prediction model, the mechanical component which is about to be failed is monitored and detected in time, the working efficiency is improved, and the failure delay time of the mechanical component is shortened.

Description

technical field [0001] The invention relates to the technical field of mechanical failure prediction, and more specifically relates to a method and device for life prediction of mechanical components of an electric drive assembly. Background technique [0002] At present, with the development of technology, mechanical industrial production has been widely used and developed rapidly, replacing most of the labor force and improving production efficiency, but at the same time, long-term electric-driven mechanical production will cause problems such as wear and aging of mechanical parts, mechanical parts It has a certain service life. If the mechanical parts are not repaired in time, when the production equipment breaks down, the production efficiency will be affected if the production equipment is stopped for repair and replacement. The most common method at present is to carry out manual inspection, and the staff will carry out non-stop inspection during production , In order ...

Problems solved by technology

[0002] At present, with the development of technology, mechanical industrial production has been widely used and developed rapidly, replacing most of the labor force and improving production efficiency, but at the same time, long-term electric-driven mechanical production will cause problems such as wear and aging of mechanical parts, mechanical parts It has a certain service life. If the mechanical parts are not repaired in time, when the production equipment breaks down, the production efficiency will be affected if the production equipment is stopped for repair and replacement. The most common method at present is to carry out manual inspection, and the staff will carry out non-stop inspection during production , in order to detect faults and repairs in time, only rely on manual experience to judge whether there is a problem with mechanical parts, it is easy to make mistakes, and usually only after a fault occurs, it can be found, so it is impossible to replace and repair mechanical parts in time
