Simulation and parameter influence analysis of the process of wheelset press-fitting for high-speed EMUs
摘要
Abstract
In order to investigate the effect of interference, friction coefficient, shape error, protruding assembly, oiling groove on the press-fit curve and stress of contact position, an axisymmetric finite element model was established by ABAQUS to simulate the wheelset press-fitting process of a high-speed EMUs. The result shows that interference and friction coefficient is the key factor to ensure the assembly quality reach the standard; Besides, protruding assembly and oiling groove have significant influence on stress of contact position; appropriate shape error combination of wheel and axle is conducive to a correct press-fitting.关键词
