【摘要】：弹复性是系统的一种特性,用来描述系统在失效或被破坏之后通过自身修复能够恢复正常运行的能力。本课题针对多振源作用下的矩形薄板系统振动失衡的问题,进行了减振方法的弹复性研究。本文提出了矩形薄板减振系统的弹复性评估体系,该评估体系作为一种新的减振系统的分析理念和方法,同时考虑了系统的失效分析和状态恢复。本文的研究目标是提出多振源作用下的矩形薄板减振系统的弹复性评估体系,通过弹复性分析实现矩形薄板系统"振动情况良好"的状态恢复。本文的主要内容有:首先,阐述弹复性的概念和特点。其次,提出矩形薄板减振系统的弹复性评估体系。最后,以矩形薄板系统"振动情况良好"状态的恢复为目标,进行详细的弹复性评估体系各个环节的论述和验证。本文的研究结果表明:(1)矩形薄板减振系统的弹复性分析不仅考虑了如何恢复系统的正常状态,而且还考虑了如何定量度量恢复策略的实施效率。(2)利用弹复性分析确定的矩形薄板系统减振恢复策略,具有不借助外部资源能自我恢复的特点。(3)通过弹复性评估体系的四个重要环节:系统辨识,失效分析,恢复策略,度量指标,成功实现了矩形薄板系统"振动情况良好"恢复状态的目标。
[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.
