Influences of the Suspension Parameters on the Vehicle Suspension Performance for a Terrain Vehicle

This paper describes an effective methodology for evaluation of the suspension parameters intended to be used for a terrain vehicle. The objective of this approach is to make quick analyses of the sensitivity of the vehicle suspension parameters. For the purpose of developing such a methodology, a mathematical modeling of a quarter vehicles suspension system is developed. Sensitive analysis of the suspension parameters is performed by employing the standard deviation of the vehicle body acceleration, dynamic tire load, and suspension travel. Sensitivity analysis results have shown that the spring stiffness, damping coefficient, tire stiffness and sprung mass have substantial influence on the ride comfort and road holding, while un-sprung mass on the other side has much lower impact in performance of the vehicle suspension system.

路灯

他抓着一张揉得皱巴巴的试卷,又破又旧的书包歪歪斜斜地挂在肩上,也不管拉链没有拉好,就这么背着。头发被风吹得凌乱,鞋带散落,垂头丧气地在地上拖行。他丝毫不予理会,梦游般地兀自向前走,走在这条被薄暮笼罩、看不见尽头的深深小巷里。路灯突然亮了,似乎把恍惚状态的他唤醒了。他停下来,下意识地抬头看看天:是啊,天黑了,人们都回家了,只有自己……在归家的小巷徘徊。
