简单介绍了驱动系统中牵引电机不同悬挂方式下的几何结构及应用范畴,从工程实际应用角度出发,基于车辆—轨道耦合动力学理论,以B_0-B_0构架为本体,建立了各悬挂方式下构架—驱动系统三刚体多自由度的“质量—刚度—阻尼”垂向振动力学模型,依据其结构的几何和运动关系,根据达朗贝尔原理列出各悬挂方式各刚体的振动微分方程,为驱动系统垂向振动的数值分析和仿真分析提供理论基础。以抱轴式悬挂系统为仿真分析对象,验证其数学模型的正确性及可靠性,并分析各刚体的振动特性。
Based on the theory of vehicle-track coupling dynamics, B_0-B_0 truss is taken as the main body, and the structure of each suspension mode is established based on the practical application of the system. Based on the principle of Darlambel, the differential equations of vibration of the rigid bodies of various suspension modes are listed according to the geometric and kinematic relationship of the three rigid bodies with multiple degrees of freedom. It provides theoretical basis for the numerical analysis and simulation analysis of vertical vibration of drive system. The axle suspension system is used as a simulation object to verify the correctness and reliability of the mathematical model and to analyze the vibration characteristics of each rigid body.
