新型压电摩擦阻尼器的有限元分析及试验研究
Finite-element Analysis and Test Study on a New Piezoelectric Friction Damper
摘要
Abstract
Using the piezoelectric effect of piezoelectric ceramics,this article developed a new pie-zoelectric friction damper based on semi-active control theory,and described its structure and working principle.The ABAQUS finite-element model of the new piezoelectric friction damper was established.By the model,the damper hysteresis curve was obtained under different condi-tions,and a hysteretic damper performance test was conducted.Simultaneously,the finite-element calculations and experimental values of the damper were compared.By comparing the hysteresis curves of the finite-element simulation and the hysteretic damper performance test,the following conclusions could be obtained.The hysteresis curve of the damper which installs one piezoelectric ceramic actuator was full,and the friction energy performance of the new piezoelectric friction damper was good;the hysteresis curve of the damper which installs two piezoelectric ceramic ac-tuators was fuller than installing one piezoelectric ceramic actuator,thus by installing two piezoe-lectric ceramic actuators,the friction damper could obtain better friction energy performance;the cause of the deviation between the theoretical and experimental values was that the driver dis-placement of the piezoelectric ceramic actuator was small and was affected by many manufactur-ing factors;so the actual output of the damper was small.Then;a model of a new piezoelectric friction damper installed on a power transmission tower was established by ANSYS;and the ac-celeration response of the layers of the power transmission tower model was computed by MAT-LAB.The friction energy performance of the new piezoelectric friction damper in the actual struc-ture could be verified.The following conclusions could be obtained through the finite-element sim-ulation:the effect of the damping control of the new piezoelectric friction damper installed on a power transmission tower was good,and the new piezoelectric friction damper had good practica-bility.This article can provide a theoretical basis for the engineering applications of the damper.关键词
