机车轮对动态检测系统过渡段设计与动态分析OA

The wear of locomotive wheelset is an unfavorable factor affecting the stability of locomotive operation.the wheel pair dynamic detection line designed in this paper is a new type of special track line for wheel pair wear state of non-parking tester,which significantly improves the detection efficiency of wheelset wear state.The track spacing of the detection line is 1 568 mm,which is wider than the standard rail gauge 1 435 mm.At this time,the normal contact area between the wheelset and the track is significantly exposed,which is convenient to detect the wear state of the wheelset.The dynamic analysis of the locomotive passing through the transition line is simulated by the finite element method,and the feasibility of the detection method is verified.The simulation results show that from the comprehensive evaluation of track strength,track deformation and wheelset carrying capacity,the wheel of this machine has strong practicability for dynamic detection line,and can meet the requirement of 23 t-axle load locomotive passing safely at 36 km/h speed,and realizes the safety inspection of wheelset wear state without parking.
