摘要

针对由磁流变阻尼器和线性弹簧组成的半挂车悬架系统，提出了一种半主动模糊逻辑控制策略。控制器的目标是通过抑制由道路不平整引起的振动来改善乘坐舒适性。在MATLAB/Simulink仿真环境下对动态系统进行了建模。在ISO 8608标准随机道路激励下，对七自由度半挂车模型的动力学特性进行仿真研究。采用Bouc-Wen模型对磁流变阻尼器的磁滞现象进行了表征。对所设计控制器的性能进行了评价，结果表明，与非受控悬架系统相比，所采用的控制算法在减振方面是有效的。

Vibration reduction of semi-trailer truck using MR dampers: A fuzzy logic control approach

This paper presents a semi-active fuzzy logic control (FLC) strategy designed for a semi-trailer truck suspension system which consists of magnetorheological (MR) damper and linear spring. The objective of the controller is to improve the ride comfort by suppressing the vibrations that result from the road irregularities. The dynamic system is modelled in MATLAB/Simulink simulation environment. Simulations are carried out under standardized random road excitation generated according to ISO 8608 to investigate dynamic behaviour of seven degrees of freedom (DOFs) semi-trailer truck model. The Bouc-Wen model is utilized to characterize the hysteresis phenomenon of the MR dampers. Performance of designed controller is evaluated and the results indicate the effectiveness of the applied control algorithm on the vibration reduction compared to uncontrolled suspension system.
