摘要

本文的目的是研究一种新设计的外孔半主动悬架系统（EOSASS）的力-速度特性。EOSASS是一类半主动系统，其中孔面积使用电动机进行电子控制。EOSASS的思想是将现有被动阻尼器的内部固定节流孔修改为使用液压单元进行外部控制。使用Instron 8801伺服液压疲劳测试系统和WaveMatrix动态测试软件，对EOSASS的力-速度和力-位移特性进行了测试。为了研究阻尼器的滞后特性，液压单元上压缩和拉伸的孔口开口面积的比率是可变的。根据实验结果，得到了拉伸和压缩过程中阻尼力与孔开口率之间的关系。研究表明，在压缩和拉伸两个阶段，减小孔口开口率都会产生更高的阻尼力。

Design and characterisation of external orifice semi-active suspension system for armoured vehicle application

The objective of this paper is to investigate the force-velocity characteristics of a new design of external orifice semi-active suspension system (EOSASS). EOSASS is a class of semi-active system where the orifice area is controlled electronically using an electric motor. The idea of EOSASS is to modify the internal fixed orifice of the existing passive damper into externally controllable using hydraulic unit. The behaviour of the EOSASS is tested in terms of its force-velocity and force-displacement characteristics using Instron 8801 Servohydraulic fatigue testing system and WaveMatrix dynamic testing software. The ratio of the orifice opening area for the compression and extension on the hydraulic unit is varied in order to study the hysteresis behaviour of the damper. From the experimental results, the relationship between the damping force and the ratio of orifice opening during extension and compression are obtained. It was verified that decreasing the ratio of orifice opening will produce higher damping force in both compression and extension stages.
