摘要:
设计一种动刚度和阻尼可调的磁流变液可控多流道悬置.首先,建立多惯性通道液压悬置模型,数值仿真不同的流道数量对悬置动刚度和滞后角的影响;然后,建立磁流变液可控多流道悬置模型,通过实验验证可控多流道可以控制流道的开闭;最后,分析磁流变液可控多流道悬置不同流道开闭的动态特性变化.结果表明:对不同的流道分别施加磁场作用可使悬置的动刚度、阻尼可调和力的传递率最小;已知激励频率,根据可控区域实时控制流道数量,可获得最佳隔振性能.
Abstract:
A controllable multi-fluid channels mount of magnetorheological fluid with adjustable dynamic stiffness and damping was designed. First, a multi-inertial channels hydraulic mount model was established to numerically simulate the effects of different channel numbers on the dynamic stiffness and lag angle of the mount. Then, the controllable multi-fluid channels mount model of magnetorheological fluid was established. The experiments verified the controllable multi-fluid channels can control opening and closing of fluid channels. Finally, the dynamic characteristic variation of controllable multi-fluid channels mount model of magnetorheological fluid opening and closing was analyzed. The results show that when the magnetic field action is applied to different fluid channels, the dynamic stiffness and damping of the mount can be adjusted, and the force transmission rate can be minimized; if the excitation frequency is known, the optimal vibration isolation performance can be obtained by controlling the number of fluid channels in real time according to the controllable area.
