【Abstract】 By simplifying 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.更多还原
