CRH2010A综合检测车测力车轮与钢轨滚动接触弹塑性分析
Elastic-Plastic Analysis on the Rolling Contact between the Instrumented Wheel of CRH2010A Comprehensive Inspection Car and Rail
摘要
Abstract
Considering three working conditions of straight line? Curve line and turnout, the nonlinear finite element software ABAQUS was adopted to construct 3D rolling contact finite element model of the instrumented wheel of CRH2010A comprehensive inspection car and rail. Analyses on the rolling contact characteristics of the instrumented wheel and rail as well as the force of wheel web and axle hub were carried through under different working conditions. Results indicate that the rolling contact characteristics of instrumented wheel are similar to those of motor car wheel. Flange effect appears and wheel wear intensifies upon crossing straight line and the lateral displacement of the wheelset is 8 mm. Left wheel and rail appear two-point contact central areas when crossing curve line. Plastic deformation occurs to both the left wheel and long point rail, also the wear of wheel and rail increases when passing through turnout. The influence by the interference fit of axle hub on wheel/rail contact characteristics is far less than that on the stress of axle hub connection and web processing area. The instrumented wheel can meet the static strength requirements under three working conditions.关键词
