Analysis of an Automatic Sliding-Plug Door Component for Failure Prevention

Abstract

An automatic sliding-plug door made of Aluminium 6005A-T6 will be implemented in the High-Speed Train project. According to risk analysis, door hinges contribute to mechanical failure during operation. A Finite element method (FEM) is used to examine the structural integrity of the design. Different loads were applied to the door structure such as interior pressure load 500 Pa and 800 Pa, passenger load 1000 N/m, and additional load in longitudinal, lateral, and vertical direction in accordance with EN 12663-1. The static structural result shows that the maximum von-Mises stress in the door panel is 41.45 MPa. At the upper hinge, the maximum von-Mises stress is 35.53 MPa. While the maximum von-Mises stress in the lower hinge is 53.28 MPa. The static result is below the yield strength of 230 MPa. The fatigue result shows that the life cycle of the structure is 10⁸, which is more than the standard life cycle of 10⁷. The results indicate that the design is safe and can be optimized to reduce weight.
