Analysis of dynamical simulation data shows as follows: Wheel tread LMA is able to satisfy the requirements of the 300 km/h~350 km/h high-speed wheel-rail technology, and wheel tread XP55 is able to reach 250 km/h~300 km/h; the main issue of Wheel tread LM is that the larger equivalent conicity may cause the bigger lateral wheel-rail force, and wheel tread S1002 has the severe problem of harmful wheel-rail wear.

动态仿真数据分析表明：LMA型车轮踏面可以满足300 km/h~350 km/h高速轮轨技术要求，而XP55型踏面则可以满足250 km/h~300 km/h速度的要求；LM型踏面的主要问题是等效锥度比较大，从而造成轮轨横向力也比较大，S1002型踏面对轮轨存在比较严重的有害磨耗问题。
