【摘要】：彈復(fù)性是系統(tǒng)的一種特性,用來(lái)描述系統(tǒng)在失效或被破壞之后通過自身修復(fù)能夠恢復(fù)正常運(yùn)行的能力。本課題針對(duì)多振源作用下的矩形薄板系統(tǒng)振動(dòng)失衡的問題,進(jìn)行了減振方法的彈復(fù)性研究。本文提出了矩形薄板減振系統(tǒng)的彈復(fù)性評(píng)估體系,該評(píng)估體系作為一種新的減振系統(tǒng)的分析理念和方法,同時(shí)考慮了系統(tǒng)的失效分析和狀態(tài)恢復(fù)。本文的研究目標(biāo)是提出多振源作用下的矩形薄板減振系統(tǒng)的彈復(fù)性評(píng)估體系,通過彈復(fù)性分析實(shí)現(xiàn)矩形薄板系統(tǒng)"振動(dòng)情況良好"的狀態(tài)恢復(fù)。本文的主要內(nèi)容有:首先,闡述彈復(fù)性的概念和特點(diǎn)。其次,提出矩形薄板減振系統(tǒng)的彈復(fù)性評(píng)估體系。最后,以矩形薄板系統(tǒng)"振動(dòng)情況良好"狀態(tài)的恢復(fù)為目標(biāo),進(jìn)行詳細(xì)的彈復(fù)性評(píng)估體系各個(gè)環(huán)節(jié)的論述和驗(yàn)證。本文的研究結(jié)果表明:(1)矩形薄板減振系統(tǒng)的彈復(fù)性分析不僅考慮了如何恢復(fù)系統(tǒng)的正常狀態(tài),而且還考慮了如何定量度量恢復(fù)策略的實(shí)施效率。(2)利用彈復(fù)性分析確定的矩形薄板系統(tǒng)減振恢復(fù)策略,具有不借助外部資源能自我恢復(fù)的特點(diǎn)。(3)通過彈復(fù)性評(píng)估體系的四個(gè)重要環(huán)節(jié):系統(tǒng)辨識(shí),失效分析,恢復(fù)策略,度量指標(biāo),成功實(shí)現(xiàn)了矩形薄板系統(tǒng)"振動(dòng)情況良好"恢復(fù)狀態(tài)的目標(biāo)。
[Abstract]:Resilience is a characteristic of a system that describes the ability of a system to recover from normal operation by repairing itself after failure or destruction.In order to solve the problem of vibration imbalance of rectangular thin plate system under the action of multiple vibration sources, the elastic reduction method is studied in this paper.In this paper, the elastic evaluation system of rectangular thin plate vibration absorption system is proposed. The evaluation system is a new analysis concept and method of vibration absorption system, and the failure analysis and state recovery of the system are also considered.The aim of this paper is to put forward the elastic evaluation system of rectangular thin plate vibration absorption system under the action of multiple vibration sources. The state recovery of rectangular thin plate system with "good vibration condition" can be realized by elastic analysis.The main contents of this paper are as follows: first, the concept and characteristics of elastic rendezvous are expounded.Secondly, the elastic evaluation system of rectangular thin plate vibration absorption system is proposed.Finally, aiming at the recovery of the "good vibration condition" of the rectangular thin plate system, the detailed discussion and verification of each link of the elastic evaluation system are carried out.The results of this paper show that the elastic analysis of rectangular thin plate vibration absorption system not only considers how to restore the normal state of the system.Furthermore, how to measure quantitatively the implementation efficiency of the recovery strategy is also considered. The resilience analysis is used to determine the vibration reduction and recovery strategy for rectangular thin plate system.It has the characteristics of self-recovery without the help of external resources.) through the four important links of resilient evaluation system: system identification, failure analysis, recovery strategy, measurement index,The goal of "good vibration condition" recovery of rectangular thin plate system has been successfully realized.
