Abstract

The bolt connection is one of the main connection ways of railway vehicles connection. The reliability of its connection determines the dynamic performance, safety and reliability of railway vehicles. Checking methods of bolt coupling strength: mechanical design calculation, finite element calculation, and "VDI2230" calculation are recognized at home and abroad. But at present, it is less to systematically analyze basic calculation flow, finite element modeling, advantages and disadvantages of these three methods, especially to check railway vehicles bolts at the same time in the three ways. This article detailed introduces the principle and characteristics of three methods. And combined with the engineering example on EMU pillow beam structure, bolt strength calculations were given. Calculation results show that using mechanical design method, the bolt model is simple and computed stress is more conservative; Using FEM, the bolt model is complex, computing time is long, computed stress is more intuitive and the stress of each part of the bolt can be given; Using VDI, the bolt model is simple, work stress is between the first two methods, calculation involves more parameters, can give a more detailed check different states at different positions of the bolt.
