Abstract

Abstract: In order to reduce the noise of cavitations for hydraulic buffer，the generating process of cavitations noise and the hydraulic oil movement in the process of compression and recovery was analyzed． The model relating the relationship between cavitations coefficients and orifice length was established． And parameter model of binocular hydraulic shock absorber was also presented． The compression and recovery process of hydraulic shock absorber was analyzed by Simulink simulation， and the relationship among cavitations noise of the buffer，orifice length and the oil kinematic viscosity was then determined． It is found that oil shock absorber cavitations noise can be reduced by adding the effective orifices diameter of throttle and decreasing the kinematic viscosity of oil．

Key words: shock absorber, cavitations, noise

摘要： 为了降低液压减振器气穴异响，分析了压缩和复原过程中液压油的运动状态和气穴的生成过程，建立了气穴系数与节流孔直径之间的关系模型，以及双筒液压减振器的参数模型; 通过Simulink 对液压减振器压缩和复原过程的仿真分析，确定了减振器气穴异响与节流孔直径和油液运动黏度的关系。结果表明: 减振器的异响可以通过增加节流阀的有效节流直径和降低油液运动黏度来减轻。
