[Abstract]:Vibration noise and energy crisis have been paid more and more attention. How to recycle vibration and noise energy distributed in the environment is a new strategic development concept of green energy. Based on piezoelectric ceramics and electrorheological elastomers, a damping electrically adjustable electrorheological elastomer damper is designed in this paper. The vibrational energy is converted into electric energy by using the piezoelectric effect of piezoelectric ceramics. It is used to adjust the damping and stiffness of electrorheological elastomer with electrorheological effect in electrically controlled vibration absorber to realize the adaptive adjustment of shock absorber and make the damper better adapt to the vibration environment. The generation performance of piezoelectric ceramics and the electrically controlled performance of electrorheological elastomer are determined by combining theory and experiment. Finally, the structure design and experimental analysis of the new damping adjustable damper are carried out. In this paper, the application of the designed shock absorber in the field of vibration control is studied theoretically and experimentally. The specific contents are as follows: 1. The research status of the two kinds of smart materials is summarized, mainly including the research status of piezoelectric energy acquisition technology. The research trends of electrorheological elastomer materials and the research status and development trends of electro / magnetorheological shock absorbers with adjustable damping designed by these two materials are discussed. The piezoelectric effects of piezoelectric ceramics are theoretically analyzed. ANSYS analysis method was used to determine the relationship between the structure size, static pressure and electricity generation performance of piezoelectric ceramics. The relationship between them was verified by experiments. Barium titanate and starch were used. Three kinds of electrorheological elastomer materials with different dispersed phases were prepared by dimethyl silicone oil and silicone rubber under different electric field conditions. The curve relationship between the force and compression modulus of three kinds of elastomers under different electric fields is obtained by using a micro universal testing machine. Finally, an electrorheological elastomer absorber with self-supply energy is designed and fabricated, and the shock absorber is experimentally measured to generate electricity in piezoelectric electricity. The results show that the damping effect is the worst under the condition of no electric field and 1000V electric field, and the damping effect is the best with the addition of 1000V electric field. The effect of the shock absorber under the condition of piezoelectric generation is between the two. Finally, it is proved that it is feasible to use piezoelectric ceramics to deregulate the damping of electrorheological elastomer.
