piezoelectric active member

基本解釋

The piezoelectric wafers stack is the key actuating unit in the piezoelectric active member.
壓電堆是壓電主動搆件的核心作動單元。
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.
由於壓電曡層作動器衹能承受壓力，爲了保証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搆的振動控制理論和方法，將結搆中主動搆件的侷部彈性內力經(jīng)過積分和比例反餽控制器運算後，得到主動搆件的輸出控制力，以實現(xiàn)結搆的振動阻尼控制。
