摘　　要：考虑动力稳定装置的轮轨非线性接触、轮轨间的间隙传动、夹钳油缸和水平油缸的等效刚度建立了动力稳定装置动态特性键合图模型。使用分段函数表达式实现了轮轨间的间隙传动。针对不同夹持力对于能量的传递效率与作业效果进行了深入分析与探究,确定了所需最小的水平油缸的推力。The roller-rail nonlinear contact of the dynamic stabilization unit,the gap transmission between the roller and rail,the equivalent stiffness of the clamp hydraulic cylinder and the horizontal hydraulic cylinder are considered to establish a complete bond graph model of the dynamic stabilization unit.A gap function transmission between the roller and rail is realized using a piecewise function expression.Based on different clamping forces,the energy transmission efficiency and working effect were analyzed and studied.
