Abstract The dynamic model of a high-speed train and the three-dimensional structural schematic diagram of the primary suspension damping of the train are established. Based on the structure, the common failure forms of the primary suspension damping of the train are studied, and the influence of the primary suspension damping failure on the running quality of the vehicle is simulated and analyzed. The results show that the common faults of primary suspension damping are mainly caused by the serious wear of the skeleton seal, the serious aging of the O-ring and the emulsification of oil. Vehicle lateral and vertical stability is less affected as one damper or two dampers (one for each bogie) are failure. The index deterioration rate is less than 5%. Comfort has a certain impact, the index deterioration rate is up to 15%. Running quality deteriorates significantly as primary suspension dampings are all failure. Comfort deterioration is the most serious and the deterioration rate of the index reaches 186%.

Key words： metrology primary suspension damping running quality of vehicle damping failure three-dimensional structure;SIMPACK
