摘  要:为了分析新型D35钳夹车重载长联挂的横向稳定性,利用模板建模技术建立了D35刚柔耦合整车模型.对于专用线路,多种曲线工况仿真分析表明:轮轨安全性(如减载率)是与导向方式相关的,如内导向R180 m曲线通过应当要求20~50 mm超高;而外导向R150 m曲线通过时则应当尽量降低顺坡率.新型D35联挂改进设计是合理的,因为车耳球铰改为车耳铰销联结后,利用钳夹梁的侧扭刚度来减小安全销相对横向位移,进而保障压柱油缸球面座的摩擦稳定性.In order to analyze the lateral stability of a new-built D35 schnabel wagon, the rigid- flexible-coupling model of the D35 full-vehicle was established with template-based modeling mothdology. For specific lines, the analyses of multi-curve simulations show that wheel/rail safety is relative to guidance modes. For example, when inner-guidance negotiation of R180m curve, the superelevation of 20 - 50 mm should be required; and when out-guidance negotiation of R150 m curve, the slope of transition section should be decreased as possible. The impored design of the D35 trailor-form is rational, since the wagon ear is connected with the heavy load by hingel joint instead of spherical articulate, and the lateral relative displacement of safety pins is very small due to the rolling stiffness of schnabel grider, so that the friction stability of spherical-surface sockets of press-down cylinders is guaranteed.
