摘要
通过简化的FR型防振锤受力模型,用模态应变能法将系统的结构阻尼等效为粘滞阻尼,运用拉格朗日方程建立防振锤的数学模型,并以此微分方程组为基础,讨论了防振锤的动力响应及能量消耗。
By implifying the force model of FR damper and making the structural damping of system equivalent to visco-damping by energy method then to establish a mathematical model with the use of Lagrange Equations. And based on this differential equations,the dynamic response and energy consumption of the damper was being discussed.
