一种磁流变阻尼器动态阻尼力模型
A dynamic model of magnetorheological dampers
【摘要】 磁流变阻尼器用于汽车悬架,可以实现理想的半主动控制,控制算法要求准确刻画阻尼力,针对有关学者提出的磁流变阻尼器的Bingham粘塑性模型、双粘性塑性模型及双粘性滞后模型,建立了基于反正切函数的磁流变阻尼器动态阻尼力模型,该模型是前三种模型的推广,其参数具有明显的物理意义,且其动态阻尼力为光滑函数,与实验象一至,最后对新模型进行了实验验证。
【Abstract】 Magnetorheological Damper is an ideal semi-active control device for vehicle suspension.The behavior of magnetorheological dampers is important for control algorithm.Based on Bingham,bi-linear and bi-linear hysteresis models,a new dynamic model with an arctangent function was presented,it was the extension of the former three models and could describe force-velocity behavior more close to the experimental data,the parameters of the model had definite physical meanings.An experiment was conducted to verify the precision of the new model.
【Key words】 magnetorheological damper; hysteresis; bi-linear model; dynamic damping force; Bingham model;
