This work proposes a new suspension system for vehicles through replacing passive ordinary suspension with a new low-cost semi-active suspension. The new proposed system consists of a hydraulic piston with proportional throttle valve mounted outside the piston’s cylinder between the two inlet ports. The throttle valve will be used to dissipate the hydraulic energy in the cylinder’s oil. The throttle valve will be controlled via artificial neural network (ANN) controller to regulate the valve opening to achieve the needed equivalent damping coefficient. The proposed system will be controlled first by a PID controller and different cases have been simulated to acquire data needed to train the artificial neural network. The proposed system is easily constructed compared with commercially available magneto-rheological (MR) damping systems with a cost down to one quarter of the (MR) dampers’ cost. MATLAB/SIMSCAPE is utilized to construct the physical model of the proposed suspension system. The response of the vehicle with the proposed low-cost semi-active suspension system will be compared with traditional suspension system and MR suspension system to evaluate the effectiveness of the proposed low-cost semi-active suspension system. The results showed good performance in terms of vibration reduction and response time compared with the MR semi-active systems and traditional systems.

这项工作提出了一种新的车辆悬架系统，该系统通过用新型低成本半主动悬架代替被动式普通悬架。新提出的系统包括一个液压活塞，该液压活塞的比例节流阀安装在两个进油口之间的活塞缸外部。节流阀将用于耗散气缸油中的液压能。节流阀将通过人工神经网络（ANN）控制器进行控制，以调节阀的开度，以达到所需的等效阻尼系数。所提出的系统将首先由PID控制器控制，并且已经模拟了不同的情况，以获取训练人工神经网络所需的数据。与市售的磁流变（MR）阻尼系统相比，所建议的系统易于构造，其成本仅为（MR）阻尼器成本的四分之一。MATLAB / SIMSCAPE用于构建所提出的悬架系统的物理模型。拟议的低成本半主动悬架系统的车辆响应与传统悬架系统和MR悬架系统进行比较，以评估拟议的低成本半主动悬架系统的有效性。结果表明，与MR半主动系统和传统系统相比，在减振和响应时间方面具有良好的性能。拟议的低成本半主动悬架系统的车辆响应与传统悬架系统和MR悬架系统进行比较，以评估拟议的低成本半主动悬架系统的有效性。结果表明，与MR半主动系统和传统系统相比，在减振和响应时间方面具有良好的性能。拟议的低成本半主动悬架系统的车辆响应与传统悬架系统和MR悬架系统进行比较，以评估拟议的低成本半主动悬架系统的有效性。结果表明，与MR半主动系统和传统系统相比，在减振和响应时间方面具有良好的性能。
