Inerter capacity is a new type of two-terminal acceleration related element.Inertercapacity system is a vibration control system composed of inerter capacity components,which has the function of energy dissipation and efficiency enhancement.However,excessive use of this mechanism may lead to greater control force,which will bring adverse effects on the inertial capacity system and structure load.So this article is based on the principle of energy dissipation efficiency of single degree of freedom structure model were analyzed,and the white noise and using the programming software,artificial seismic wave,high frequency seismic wave and seismic wave frequency used for suspension structure under seismic excitation,seismic response analysis is used to permit system applied to practical engineering provides strong theoretical support,the main research content is as follows:（1）In order to control the efficiency of the inerter capacity system and limit the control of the inerter capacity system,it is necessary to find a kind of energy efficiency control method,but the existing control method needs to solve more complex nonlinear equations and is inconvenient to use.Therefore,in order to control the efficiency of the inerter capacity system more conveniently,a design method based on the principle of the efficiency of the target energy consumption is put forward to solve the analytical design formula of the inertial capacity shock absorption system,which simplifies the design calculation process.（2）The random vibration theory is used to analyze the dynamic response of typical inerter capacity shock absorption system with single degree of freedom,and the corresponding analytical expression of random response is obtained.Based on target principle of efficiency,energy consumption and energy efficiency design principle is derived under the premise of considering damping demand compound Ⅰ type and mixed type Ⅱ spoil should the system be used mass ratio,stiffness ratio and damping ratio in the name of analytical form of the optimal solution,through a given expected the equivalent damping ratio and the energy dissipation efficiency than required,can be directly used to determine the key system parameter values.（3）A series of inerter capacity damping structures with different damping requirements are designed by using the targeted energy dissipation enhancement design formula,and the performance is verified by the dynamic time history under the action of ground motion.Based on the results,the correctness of the targeted energy dissipation enhancement design formula and the feasibility of the design method are discussed.（4）The particle swarm optimization algorithm with good robustness and simple principle is chosen as the solution method to optimize the inerter capacity shock absorption system.On the basis of the optimization problem and the analytical expression,an adaptive weighted particle swarm optimization algorithm program is programmed in Python language to solve the target energy dissipation efficiency design problem of inerter capacity shock absorption system.Through the example design and verification,it is proved that this method can realize the control of energy consumption efficiency of inerter capacity system on the premise of meeting the performance requirements.By verifying the performance of the algorithm,it is proved that the self-adaptive weighted particle swarm optimization algorithm is easy to implement and has strong solving ability,which is an effective means for optimal design of damping structures.
