　　针对车轮啃轨这一常见但长期未得到有效解决的难题，提出一种车轮单侧弧型踏面结构，即起重机一侧车轮由优化的参数化弧形踏面替代平面踏面，改变轮轨的接触形式；而另一侧仍采用平面踏面对轨道的跨距误差进行补偿。建立轮轨接触理论仿真模型，分析车轮踏面的弧形结构参数对于接触应力、摩擦力及啃轨的影响。通过QD35-28.5双梁桥式起重机试验和现场应用验证该技术对于解决起重机啃轨问题的有效性。

Aiming at the common problem of wheel rail-biting which hasn't been effectively solved for a long term, a wheel unilateral arc-tread structure is put forward in the paper, that is, the optimized parametrical arc-tread of the crane wheel on one side is used to replace the plane tread, in order to change the contact type of wheel and rail; while the plain tread is employed on the other side to compensate for the rail span error.The wheel-rail contact theory simulation model is built to analyze the effect of arc structure of wheel tread on the contact stress, friction force, and rail biting.The test for QD35-28.5 double-beam overhead crane is carried out, with further site application to verify the effectiveness of such tech-nology to solve the crane's rail-biting problems.
