摘要
采用键合图理论建立了单出杆双筒双线圈磁流变减振器阻尼力模型。首先结合本文设计的磁流变减振器结构,基于平行板下流量模型和键合图理论,建立了该减振器键合图模型,得出了考虑减振器运动位移、速度及加速度的阻尼力模型。基于该减振器阻尼力理论模型进行了减振器不同电流、速度下示功特性和速度特性仿真,并和减振器台架试验结果进行了对比,发现其示功特性曲线和速度特性曲线理论仿真与试验结果吻合。对减振器施加2A电流,运动速度为0.26 m·s-1时,减振器阻尼力误差最小,为5.2%。对减振器不加载电流,运动速度为0.052 m·s-1时,减振器阻尼力误差最大,为7.2%。
Based on the bond graph theory,the damping force model of a single-rod,double-cylinder and double-coil magneto-rheological(MR)damper was established.Firstly,based on the flow model under the parallel plate and bond graph theory,the bond graph model of the damper was established,and the damping force model considering the displacement,velocity and acceleration of the damper was obtained.Based on the theoretical model of damper damping force,the simulation of the force-displacement and force-velocity characteristics of the damper under different current and velocity was carried out,and compared with the results of the damper bench test,it was found that the theoretical simulation of the force-displacement and force-velocity characteristics curves agreed well with the simulation results.When 2 A current was applied to the damper and the velocity was 0.26 m·s-1,the damper force error was the smallest,which was 5.2%.When the current was not applied to the damper and the velocity was 0.052 m·s-1,the damper force error was the largest,which was 7.2%.
