摘要
针对可变串联阻尼孔减振器外特性的特点,提出了其主要参数的设计方法.建立了整车7自由度数学模型,以提高整车的瞬态响应特性、平顺性、车轮接地性为目的,对某越野车的串联阻尼孔可调减振器外特性进行了设计.结果表明,采用串联阻尼孔可调减振器的越野车辆,其在不同的路面上均有良好的操纵稳定性和平顺性,越野车速也有所提高.
According to the features of external characteristics of shock absorber whose series orifice is variable, a design approach of its key parameters is put forward. A mathematical vehicle model of a seven-freedom was built up and solved in order to design the key parameters of shock absorber whose series orifice is changeable. The purpose to optimize external characteristics of shock absorber is to improve the transient response characteristic, riding and wheel ground adhesion index. The results indicated that using such a kind of shock absorber, the stability and comfort of off-road vehicles are acceptable, and the speed on rough road is increased.
