Summary:The invention relates to a test method for rail system wheel-rail coupling dynamic characteristics of rail transportation. Under the condition of wheel-rail coupling (30), excitation force (41) is applied to a steel rail head (24) and a wheel rim (13) separately, dynamic response of a rail system (20) and a wheel shaft system (10) is measured, and wheel-rail coupling dynamic characteristic parameters are obtained through characteristic analysis of the excitation force and the dynamic response. The wheel-rail coupling dynamic characteristic parameters include a corresponding frequency responsefunction obtained and measured by the excitation force and the dynamic response, and the dynamic characteristic parameters of the rail system (20) and the wheel shaft system (10) obtained by the frequency response function. Compared with the prior art, the test method for the rail system wheel-rail coupling dynamic characteristics of rail transportation accurately reflects the dynamic characteristics of the rail system in
