一種壓電摩擦阻尼器的半主動(dòng)控制研究
[Abstract]:The vibration control methods of the structure can be divided into passive control, semi-active control, active control and hybrid control. In recent years, intelligent control is the leading technology of international vibration control research. Piezoelectric friction damper made of piezoelectric materials is a kind of intelligent control device. In this paper, a piezoelectric friction damper is proposed based on the inverse piezoelectric effect of piezoelectric material and the equivalent spring stiffness theory. The control effect of the damper is numerically simulated by semi-active control algorithm. The main contents are as follows: 1) by studying the physical and mechanical properties of piezoelectric materials, a numerical model is established by using finite element software, and the results are compared with the performance of piezoelectric materials in order to verify the correctness of the numerical model. Through the Python secondary development interface of ABAQUS software, the program script is written to realize the duplication of stack chips. The preprocessing operation of stacking chip loading voltage and material attribute. 2) theoretical analysis of the piezoelectric friction damper designed by using the equivalent spring stiffness theory; The energy input and mechanical energy output principle are used to optimize the shell size of the damper. Through numerical simulation, the curves of the relationship between force and displacement of dampers with different loading voltages under harmonic displacement regime are obtained. 3) genetic algorithm is used to optimize the QR weight matrix of the LQR control algorithm, and the displacement of the structure is obtained. The acceleration and damping force of the damper are used as the reference target to establish the fitness function. After the optimal selection and the artificial trial calculation, the structure control effect is compared between the two conditions, which are formed by the QR weight matrix, and it is concluded that the optimized control function has a better control effect on the structure. The feasibility of genetic algorithm for searching global optimal response value is verified. 4) an improved Bang-Bang control strategy is proposed to control the input voltage of piezoelectric friction damper. The piezoelectric friction damper can control the floor displacement and the acceleration of the structure. Numerical simulation shows that the piezoelectric friction damper can control a three-story steel frame structure under the improved control strategy. The results show that the piezoelectric friction damper has a better control effect on the floor displacement and acceleration of the structure.
