Abstract

Article history Received: 25 February 2020 Accepted: 27 March 2020 Published Online: 31 March 2020 It is well-known that suspension systems plays a major role in automotive technology. Most of the today’s vehicle applies a passive suspension systems consisting of a spring and damper. The design of automotive suspension have been a compromise between passenger comfort, suspension travel and road holding ability. This work aims in reducing the suspension travel alone by developing a quarter car model suspension for a passenger car to improve its performance by introducing shape memory alloy spring (Nitinol) instead of traditional spring. A two way shape memory alloy spring possesses two different stiffness in its two different phases (martensite and austenite). In this study, road profile is considered as a simple harmonic profile and vibration analysis of aminiature quarter car model suspension system has been carried out experimentally. Using theoretical method, the displacement of the sprung mass is also studied and discussed. The vibration analysis have been carried out for the suspension system at both phases of the spring and the results gives a significant improvement in reducing the displacement of sprung mass for various excitation frequencies.

基于形状记忆合金的四分之一汽车悬架系统的研制

文章历史收稿日期:2020年2月25日接收日期:2020年3月27日发布日期:2020年3月31日众所周知，悬架系统在汽车技术中发挥着重要作用。今天的大多数车辆采用由弹簧和阻尼器组成的被动悬架系统。汽车悬架的设计一直是在乘客舒适性、悬架行驶和道路持稳能力之间做出妥协。本工作旨在通过开发乘用车四分之一汽车模型悬架，通过引入形状记忆合金弹簧(镍钛诺)代替传统弹簧来改善悬架的性能，从而减少悬架的单独行程。双向形状记忆合金弹簧在两种不同相(马氏体和奥氏体)中具有两种不同的刚度。本研究将道路轮廓线视为简谐轮廓线，对微缩四分之一汽车模型悬架系统进行了振动实验分析。用理论方法对簧载质量的位移进行了研究和讨论。对悬架系统在弹簧的两个阶段进行了振动分析，结果表明，在不同的激励频率下，悬架系统在减小簧载质量位移方面有显著的改善。
