摘要：

The static stiffness of some arm positioning rubber nodes from 3 manufacturers was carried out. These arm positioning rubber nodes had been in service for 1.2 million km reaching the advanced maintenance on CRH3 EMUs of Beijing-Shanghai and Wuhan-Guangzhou high-speed railways. The stiffness variation ranges of arm nodes from different manufacturers on different operating lines were analyzed. The dynamics simulation model of CRH3 EMU trailer was established and verified by using the Simpack multi-body dynamics software. The influence of the stiffness variation on the dynamic performance of vehicle was studied and analyzed when matching the 60N and 60D rails respectively. The results show that after being in service for 1.2 million km, the radial stiffness distribution is between 85.1 MN · m-1 and 158.5 MN · m-1, and the radial stiffness change rate is within the distribution range of -38.9%-18.6%. There are great differences in the stiffness variations of arm nodes produced by various manufacturers, while the stiffness variation ranges of those produced by manufacturer A used on Beijing-Shanghai and Wuhan-Guangzhou high-speed railways are similar. With the increase of the longitudinal stiffness of the arm node, the nonlinear critical speed of the vehicle decreases, and the sperling index, wheel-axle lateral force of wheelset, wear power and other indexes increase. Moreover, the dynamic performance indexes of 60D rail are greater than those of 60N rail, but all of them are far less than the safety limits. When the longitudinal stiffness of arm rode is greater than 140 MN · m-1, the CRH3 EMU is more sensitive to the variation of 60D rail profile and it is prone to abnormal vibration caused by too low equivalent conicity. © 2021, Editorial Department of China Railway Science.
