Abstract

In this paper

the structural characteristics of the power pack in dual-power high-speed multiple-unit trains were present‐ ed. The finite element model of the power pack frame was established using HyperMesh

and the static strength and fatigue strength con‐ ditions of the power pack frame were determined based on EN 12663-1. The static strength of the power pack frame structure was evalu‐ ated using Von mises stress theory

and the welding fatigue strength according to DVS 1612. ANSYS software was utilized for free mode analysis of the power pack frame

while a dynamics model was developed on the basis of the double-layer vibration isolation theory. Vi‐ bration intensity of the power pack was calculated following ISO 10816-6

and vibration tests were conducted on the power pack frame in accordance with ISO 8528-9. Through simulation analysis and vibration tests on the power pack frame

the results show that the power pack frame satisfies the design requirements specified by relevant standards.
