依弹性体理论 ,用“假想层”法分析了由不同材料组成的连接铰摩擦接触面间的阻尼特性 ,在 Iwan描述模型的基础上 ,导出了包括弹性变形、部分滑移、整体滑移三种状态在内的接触面上的力与位移弹塑性滞迟模型 .可用于分析配合接触面的能量传递关系及其对系统动力特性的影响 ,为振动的主动控制获得更精确的数学模型提供有力的参考 .
According to the theory of elastomer, the damping characteristics of friction joints between joints made of different materials were analyzed by the “imaginary layer” method. Based on Iwan’s description model, the elastic deformation, partial slip, This model can be used to analyze the energy transfer of the mating interface and its influence on the dynamic characteristics of the system and provide a powerful force for the more accurate mathematical model of active vibration control The reference.
