现代铁路减震器的设计考虑了几何形状、功能、耐用性和强度。概述了减震器的工作原理。描述了用于车辆舒适性和稳定性动力学研究的新型减震器模型的开发。该模型计算阻尼力作为活塞杆相对于阻尼器体的位移和速度的函数。描述了进气阀、阻尼阀、状态变量、油、油流组件和橡胶附件的建模。概述了压力模型中的假设。该模型可以分析减震器本身的动力学和功能以及与车辆的动态相互作用。给出了描述流向每个工作室的油流、累积项中的系数C、有效压缩模量、活塞上的力和活塞位置的状态方程。
The design of modern railway shock absorbers takes into account geometry, functionality, durability and strength. The working principles of a shock absorber are outlined. The development of a new shock absorber model for use in vehicle dynamics studies on comfort and stability is described. The model calculates the damper force as a function of the displacement and velocity of the piston rod in relation to the damper body. Modelling of the intake valves, damping valves, state variables, oil, oil flow components, and rubber attachments is described. The assumptions in the pressure model are outlined. The model makes it possible to analyse the dynamics and functionality of the shock absorber itself and the dynamic interaction with the vehicle. The state equations describing the oil flow to each working chamber, the coefficient C in the accumulation term, the effective compression modulus, the force on the piston and the position of the piston are presented.
