针对既有的无缝道岔设计理论与方法的局限性,结合12号拼装式合金钢辙叉提速道岔结构的特点,采用有限元方法、并结合优化的当量阻力法对拼装式合金钢辙叉结构在无缝化时的适应性进行对比研究分析,并在研究的基础上,就此种辙叉结构无缝道岔的使用范围提出建议。
Aiming at the limitations of the existing design theory and method of seamless turnout, combined with the characteristics of 12-speed welded turnout with integrated alloy steel, the finite element method and optimized equivalent resistance method In the seamless adaptability comparative study and analysis, and on the basis of the study, the use of such frog seamless turnout range proposed.
