常見例句雙語例句The piezoelectric wafers stack is the key actuating unit in the piezoelectric active member.壓電堆是壓電主動構件的核心作動單元。As the piezoelectric stack actuator can withstand pressure only, a preload device is designed to ensure that the intelligent active member can experience tensile stress.由于壓電疊層作動器只能承受壓力，為了保證壓電智能主動桿能夠承受一定的拉力，設計了預壓裝置。This paper presents the results of active damping realized by a piezoelectric active member to control the vibration of a four-bay four-longern aluminum truss structure with cantilever boundary.本文主要研究自適應桁架結構的振動控制理論和方法，將結構中主動構件的局部彈性內力經過積分和比例反饋控制器運算后，得到主動構件的輸出控制力，以實現結構的振動阻尼控制。 返回 piezoelectric active member
