Abstract

High-speed railway propose higher requirements on the bogie technology，in order to design a super performance of electric multiple unit （EMU） bogie， investigate the line condition of China passenger dedicated railway，and also investigate the wheel tread wear of EMU，use actual measurement rail profile and worn profile tread analysis the matching relationship of wheel and rail. Dynamics analysis consider nonlinear characteristics of box guidance node，anti-hunting damper，air spring and other parts，and consider the parameters changes at different high and low temperature variations，also consider motor elastic suspension mode，basic on above factor，build vehicle dynamics model with actual wheel rail matching relationship，through system simulation optimal selection of suspension parameters，combined with the test stand construction design. In order to grasp the key parts of bogie service period reliability，take a great deal dynamic stress test，use the test data analysis maintenance vehicle operating cycle，different climatic conditions，different line conditions on the ballastless track of China，setup China high-speed train load spectrum. Through system integration of the structure design，suspension，transmission，brake，wheel rail noise，structure welding and so on，the high-speed train bogie technology system was founded.
