- Average characteristic sensitivity
平均特性灵敏度 - Local sensitivity analysis ( sa ) and global sa are presented in this paper , including the mostly used means for structural dynamics behavior sa along with the their disadvantages
本文分别介绍了局部灵敏度和全局灵敏度分析方法以及结构动态特性灵敏度分析的主要手段并指出其中的不足。 - The structural dynamic sa in project is of great importance for the study on dynamic design , optimization design , control theory and dynamic modification etc . and direct method , difference method and perturbation method for dynamic sa are adopted regular , though following shortages are obvious : only local impact of the factors on the model can be obtained ; model dependence ; the interval is usually the same for all of the variables and is not related to our degree of knowledge of the variables ; shortage of precision and so on
工程结构的动态特性灵敏度分析对工程结构的动态设计、优化设计、控制理论和动态修改等方面的研究有着十分重要的意义。目前，结构动态特性灵敏度的分析法一般采用局部法，如直接法、差分法和摄动法。但是这些方法只能求参数域某点的灵敏度，不仅受模型、计算精度的限制，而且二阶以上的灵敏度求解比较困难。
