"VDI2230" calculation is a checking method of bolt coupling strength, which is recognized worldwide. The calculation and selection of the key parameters involved in the checking process are explained, and the finite element modeling strategy of the bolt is given. Combined with the engineering example on EMU pillow beam structure, the calculation data and strength results of the key parameters are given concretely. Calculation results show that the coupling bolts of the EMU pillow beam meet the requirements of various safety coefficients in the VDI2230 standard. The conclusion provides technical reference for the engineering calculation of the bolt connection of the rail vehicle.
