Abstract

The servo system is one of the key components of industrial robots. How to quickly shorten the development cycle of the servo system and improve its reliability is an urgent problem to be solved in the development of industrial robots. Highly accelerated life test (HALT) techniques can play an important role in servo system reliability study. Based on the characteristics of servo system, a method for HALT of servo system is proposed and the implementation process of HALT of servo system is described. Furthermore, a typical servo system is selected to carry out HALT to find out its weaknesses and stress limit. The case shows that HALT can quickly and efficiently expose the weaknesses of the servo system, which has certain reference value for improving the reliability of the servo system.
