Reliability analysis of the optimized carrying door frame based on six-sigma

Abstract

The door frame is a key component of the track door system. This paper uses the Six-sigma Analysis module in the finite element software ANSYS Workbench to analyze the reliability of the door frame, and regards its geometric dimensions and materials as random variables. Test design, Latin hypercube sampling, and Monte Carlo simulation calculations respectively obtained the reliability values of static strength and static stiffness of the door frame. The reliability values were analyzed to verify the rationality of the design.
