composite monitor 中文意思是什麼
composite monitor
解釋
復合式監視器-
This study adopts active detection technique based on lamb wave to monitor damage in composite materials. pzt ceramics with the diameter of 8mm are bonded on the surface of fiberglass - reinforced composite material acting as both actuators and sensors to generate and collect lamb waves. the waves emitted interact with discontinuities and experience a change in their propagation characteristics when damage is generated
本文採用lamb波主動監測技術，利用粘貼在復合材料板表面的壓電元件，通過選擇恰當的激勵信號，激勵出可進行lamb波分析的主動監測信號，進而對監測信號進行分析及模式處理，初步實現了二維結構的損傷定位。 -
Different characteristic parameters fitting for different damage detection methods are extracted from the filtered sensors signal by hht technology. at last, the location and the degree of damage in the composite material can be determined by using defferent damage detection methods. this study adopts active detection technique based on lamb wave to monitor damage in composite materials
並且針對每種損傷定位方法選擇有效的描述結構損傷的特徵參數，利用四種不同的方法對結構進行損傷定位和損傷程度的識別，通過實驗證明，這四種損傷識別方法均能有效準確的識別出損傷位置和損傷程度。 -
Experimental specimens embedded with superelastic wires, which are rectangle laminated composite panels with a circular hole and square plate, were prepared to make respectively tensile and bending test. the outputs of sensors embedded in structures were timely acquired to monitor mechanical properties of structure
對含孔洞的典型構件進行拉伸試驗，對方板構件進行彎曲模擬受載試驗，實時採集結構中傳感元件的輸出，以實驗的方法監測結構宏觀力學行為。
