Based on the theory of hydraulic cylinder design and physical properties of mrf , a mechanical model of mrf dampers with mixed mode of pressure - gradient flow and shear flow in a single cylinder was developed , the parameters of mrf dampers were simulatively investigated numerically , the relationship of damping to the clearance between the cylinder and piston , piston velocity , and mrf viscosity was obtained , and the optimal mrf damper ' s designing parameters were determined
摘要基于液壓流體力學(xué)的液壓缸設(shè)計(jì)理論，由磁流變液的物理性質(zhì)建立了單筒壓差流動(dòng)和剪切流動(dòng)混合模式磁流變液阻尼器的力學(xué)模型，用數(shù)值計(jì)算方法對(duì)磁流變液阻尼器的參數(shù)進(jìn)行了模擬仿真研究，求得缸體和活塞之間的縫隙、活塞的運(yùn)動(dòng)速度及磁流變液的粘性系數(shù)與阻尼力之間的關(guān)系，確定了最佳的磁流變液阻尼器設(shè)計(jì)參數(shù)。
