摘　　要：以某型号一系垂向减振器的实际结构参数为基础,利用流体力学和油膜理论,建立了考虑泄漏的油压减振器的数学模型。根据油压减振器的具体参数和公式,在MATLAB/Simulink中建立了减振器的系统仿真模型。利用所建立的仿真模型,分析了单一变量下阻尼阀截面积、活塞杆面积、活塞面积、弹簧预压缩量等减振器关键参数对减振器阻尼性能的影响,为减振器的阻尼特性优化设计提供了参考。Based on the actual structure parameters of one type vertical damper, making use of the fluid mechanics and film theo- ry, the mathematical model considering the leakage of the hydraulic damper was built. According to the specific parameters and formu- las of the hydraulic damper, a system simulation model of the hydraulic damper was created in MATLAB/Simulink. The established simulation model was used to analyze the effects on the damping of the damper under a single variable resuhed from the cross-sectional area of the orifice valve, the areaof the piston rod and the piston, the Spring pre-compression and other key parameters of the damper. It provides reference for the damping optimization design of the damper.
