车辆振动磁流变阻尼器的受力过程参数建模

Stress Process Parameter Modeling of Vehicle Vibration Magnetorheological Damper

应用半主动控制悬架系统提高车辆的乘座舒适性和操纵稳定性的研究受到了学术界和工业界的广泛关注。在对磁流变液体和磁流变阻尼器的特征分析的基础上,传统的车辆振动磁流变阻尼器受力分析模型以单个分析目标为主,忽略了多目标分析的需求。为此,设计了一种新的对于磁流变阻尼器性能分析的数学模型,通过简化的平板结构,得出了剪切阀式磁流变阻尼器和阀式阻尼力之和的混合环境下阻尼力参数计算公式,揭示出了阻尼力与工作电流、活塞运动速度及结构参数之间的内在联系,并以此模型为依据,进行某车型的剪切阀式磁流变阻尼器的受力分析实验,经实验研究其性能良好。

Application of semi-active control of suspension system to improve vehicle ride comfort and handling stability re-search has received the widespread attention of academia and industry. In magnetorheological fluids and based on the anal-ysis of the characteristics of the magnetorheological damper, the traditional mechanical analysis model is given priority towith individual analysis target, ignoring the multi-objective analysis needs. To this end, we design a new magnetorheologi-cal damper for performance analysis of mathematical model, by simplifying the flat structure, it is concluded that the shearvalve type and valve type magnetorheological damper damping force of the damping force parameter calculation formula ofmixed environment, reveals a damping force and the working current, piston velocity, and the intrinsic relationship betweenthe structural parameters, and based on this model, some models of shear valve type magnetorheological damper force analy-sis of the experiment, the experimental research on its performance is good
