摘要

The strength of the key parts and associated coupling bolts on the high-speed car body, which have direct related to the safe operation, is an important content of vehicle design. Nonlinear static strength analysis of mounting bracket on EMU inner end door was calculated on 8 working conditions with ANSYS software and very part was assessed. Then, sliding coefficients of hanging bracket on the most dangerous condition were analyzed. Results show that contact surface sliding coefficients were less than 1, the hanging bracket is safe and is not prone to sliding. Finally the influence of the sliding coefficient and bolt strength based on different preload was studied. With the preload becoming increasingly, the sliding coefficient became smaller and the bolt stress became larger. Taking the both influence into consideration, a proper range of the preload meeting the design requirements was obtained to provide some technology reference on the structural design and selection of bolts for engineers.
