Reliability Analysis of ABB IRB 4600-40-255 Polishing Robot with Six Degree of Freedom

摘要

Fault tree analysis, as an effective method for reliability analysis and evaluation of engineering systems, provided an effective method for failure analysis of polishing robots with six degree of freedom. Through the qualitative and quantitative analysis of the fault tree, it is proposed that the damage of the control electrical system is the main reason for the failure of polishing robots with six degree of freedom. This article aims to make a more comprehensive and systematic analysis on the reliability of the polishing robots with six degree of freedom, which has an important reference value for the design of the polishing robot.
