摘　　要：为了提高制备的液压放大自修复静电驱动器(Hydraulically Amplified Self-healing Electrostatic Actuators,HASEL)的性能,课题组以输出力和形变量表征该驱动器的性能,并采用控制变量法探究了注液量、介电油类型、驱动器长宽尺寸和预压力对驱动器性能的影响。结果表明:在相同电压下,随着注液量的增大,输出力和形变量呈现先增大后减小的趋势;硅油相较于其它几种介电油表现出更高的输出力和形变量;驱动器尺寸对输出力和形变量影响较小;预压力对驱动器的输出力有着较大的影响,合适的预压力可以提高输出力。该新型柔性驱动器结构简单、驱动性能优异、响应迅速,并具有液体电介质击穿后的自修复功能。In order to improve the performance of the Hydraulically Amplified Self-healing Electrostatic Actuators(HASEL)prepared,the research team characterized the performance of this actuator by means of output force and deformation quantity,and investigated the influences of injection volume,dielectric oil type,length and width dimensions of the actuator,and preload on the performance of the actuator.The results indicated that:with the increase of the injection volume,the output force and deformation quantity present a trend of first increasing and then decreasing at the same voltage;compare with several other dielectric oils,silicone oil exhibit higher output force and deformation quantity;the size of the actuator has a relatively small impact on the output force and deformation quantity;the preload has a considerable influence on the output force of the actuator,and providing an appropriate preload to the actuator can enhance the output force.This actuator is a new type of flexible actuator,featuring a simple structure,outstanding driving performance,rapid response,and a self-healing function after the breakdown of the liquid dielectric.
