The Structural Design And Experimental Research Of Self-energized Ere Shock Absorber

The vibration noise and the energy crisis have get a lot of attention, how to recovery the vibration noise of energy that distributed in the environment, it is a new strategic development idea about the green energy. On the basis of the intelligent material piezoelectric ceramics and electrorheological elastomer, the electric control of the self powered electrorheological elastomer damper has been designed in this article, using the piezoelectric effect of piezoelectric ceramic the vibration energy converted into electrical energy to control with current electrorheological effect of elastomer damper,realized adaptive damper adjustment,and be better adapted to the environment of vibration damper. In this essay, the theoretical and experimental methods have been adapted that determined the electrical properties of piezoelectric ceramics and the power performance of the electrorheological elastomer, measured self powered vibration experimental data of Electrorheological elastomer damper.This article will theoretically and experimentally studied the application of damper design in the field of vibration control. The specific contents are as follows:1.The research about the present situation on two kind of intelligent materials are summarized, including the research on current piezoelectric energy harvesting technology, study on dynamic electrorheological elastomer material and the use of the design on two kinds of material damping adjustable electric / research status and development of magneto rheological damper dynamic.2.The piezoelectric effect of piezoelectric ceramic materials were analyzed by ANSYS tanalytic technique, the analytical method to determine the size of the material’s structure, the static relationship between the pressure and the piezoelectric ceramic power performance, and verify the relationship between the three experimental.3. Using barium titanate, starch, two methyl silicone oil and silicone rubber material in the different electric field that were produced in three different current dispersed phase variable elastic material, make the use of micro universal testing machine the curve relationship of three elastic bodies between different electric field force and compression modulus is obtained.4.Finally, designing and manufacturing the self powered electrorheological elastomer damper, the experimentally measured the shock absorber damping data respectively under the condition of 1000 V electric field is applied to the piezoelectric power generation, no field and experimental data, the summary analysis found no electric field under the conditions of the damping effect is the worst, plus the damping effect of 1000 V electric field is the best, and the effect of the shock absorber under the conditions of piezoelectric power between the two, the experiment finally proved that the use of piezoelectric ceramics to controlled electrorheological elastomer damping is feasible.
