摘要

设计、制作了阻尼力可调范围大、位移不受限制的旋转剪切式MR阻尼器,进行了MR阻尼器力学性能试验,提出了MR阻尼力库仑摩擦阻尼力峰值与输入电流的玻尔兹曼函数关系。分析了MR阻尼力时程,MR阻尼力与位移、速度关系,以及振动频率、幅值和电流对MR阻尼力的影响。对比MR试验值与基于玻尔兹曼函数Bingham模型值的关系,证明了基于玻尔兹曼函数的Bingham模型是合理的。




Abstract

The rotary-mode shear MR damper was designed and manufactured to meet larger continuously adjustable damping force and unrestricted displacement. The Boltzmann function formulation of relationship between the peak of coulomb friction damping force of MR damper and its input current was investigated based on mechanical properties test results of MR damper. The time history of MR damping force, the relationship of MR damping force and displacement, the relationship between MR damping force and velocity, the impact of vibration frequencies and amplitudes, the impact of input current were analyzed. By comparing experimental analysis of damping force time history, relation of damping force and displacement, and relation of damping force and velocity, with Boltzmann function analysis of those, it was further proved that Bingham model based on Boltzmann function was reasonable..
