Strength Calculation Based on Contact Nonlinear Analysis of Coupler Bolt with Three Methods

Abstract:

Bolts as the key connection parts are directly related to the safety of high-speed train. Contact nonlinear static strength of CRH (China Railway High-Speed) coupler bolt was analyzed on traction and compression load with ANSYS software. According to maximum stress of bolts was appeared on tension load, CRH bolt strength was evaluated and compared based on three methods: finite element analysis (FEA), "Verein Deutscher Ingenieure 2230 standard (VDI 2230)" and “Mechanical Design Handbook”. The results show that the axial tensile stress is much greater than the shear stress and gradually increase with three methods.
