轿车减震器的设计

摘 要

本文设计出适用于中国一般城市道路使用的双作用筒式减振器。首先,根据轿车的质量算出减振器的阻尼系数,确定缸体结构参数,然后建立流体力学模型,先选定一条理想的减振器标准阻尼特性曲线,然后利用逼近理想阻尼特性曲线的方法,进行各阀、系的设计计算;在此基础上,设计出整个减震器,并对主要部件的强度进行了校核。

Shock Absorber Design of car

Abstract

The double use of drum shock absorber which applicable to the general city road conditions in China is designed in the paper. First of all, the damping coefficient of the shock absorber is calculated according to the quality of car. The parameters of the cylinder structure are determined. And then a hydrodynamic model is set up. The valve and the Department are calculated and the designed by using the way of approach to the damping characteristics of the ideal standard shock absorber curve. After that a set of the double use of drum shock absorber is designed. The strength of the main parts of the shock absorber is checked.

Key words: Double use of shock absorber; hydrodynamic model; characteristics of the

ideal curve; strength checking
