摘要
建立了能形象直观反映无缝道岔实际工作状况的力学模型，并以此研究了我国刚研制的３０号高速道岔无缝化后主要设计参数对钢轨的温度力与位移的影响规律，得出的结论可直接指导３０号无缝道岔的设计。
A mechanical model that can visually demonstrate the real structure of switch 30, which has been developed recently in our country, has been established. Based on this, the influences of main design parameters of welded switch by the rail temperature stress and displacement have been studied, and the conclusions which have important guiding significance in practice were obtained.
