摘要
模态是结构系统的固有振动特性,结构的模态属性一般由有限元计算和/或实物试验方法得到,依据模态属性可以对结构的动态特性进行预估和优化,也可以通过结构的整体或局部模态特性诊断、预判结构系统的故障。在铁路货车行业,模态分析已经是一种常规的分析项目,对于如何使用模态分析结果对结构的损伤情况进行预判也有人进行过论述,但终是没有得到普遍应用。本文通过使用该方法对已有结构的故障进行实例分析,论证该方法的可行性,如果使用该方法能够实现故障诊断,那么理论上该方法就能够应用于结构危险部位的预判。对于结构危险部位的预判是设计中一个重要的环节,通过预判可以找到结构的薄弱点,知道了薄弱点就可以在结构设计过程中通过改进总体、局部结构或者通过特殊装置来屏蔽或消除危险点,提高结构的安全性和设计质量。
Modal is the inherent vibration property of structure system. Structure modal property can be obtained from FEA and/or physical tests,and then used to predict or optimize structure dynamic performance. Structural whole or partial modal features can be used to diagnose or forecast structure failures. For railway freight wagons,modal analysis has become a conventional analysis and there are papers on how to use modal analysis to forecast structure damage. However modal analysis still has not been widely used. This paper demonstrates the feasibility of modal analysis on structural failures by examples. If it can be used to diagnose failures,in theory it can be used to predict dangerous spots in structure. Such prediction is very critical in design,as it can be used to find weak spots of structure and then to block or eliminate such weak spots by optimization of partial or overall structure in design or use of special device so as to improve safety and design quality of structure.
