一种磁流变阻尼器动态阻尼力模型
|
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。
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.
