piezoelectric active member

基本解释

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杆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，以實現結搆的振動阻尼控制。
