The rail is the most important load-bearing part in the railway system.The wheel-rail load increases during the train operation,various track defects such as corrugation,fatigue crack and spalling are becoming more and more serious.These track damage aggravates the noise and vibration of the train,even endangers the safety of the train.Rail grinding car is the most effective measure to repair rail in railway public affairs depart-ment at present.It can reduce and repair the rail damage,improve the wheel-rail matching performance,prolong the service life of rail and improve the stability and safety of train operation.In this paper,ANSYS software is used for rail grinding car modeling and finite element calculation and analysis,and the test results are compared with the finite element analysis,ensure the strength and stiffness of the body structure meet the test standards requirements,and accumulate experience for other vehicle design.
