Focusing on the application of modes parameter sensitivities in some practical construction fields such as structural optimization,modal updating and damage identification,the authors introduce the usual algorithms,and establish a unique but simple mathematic model with the combination of these three applied fields.In this paper,we reveal the interrelationship between mathematic models,and analyze the technique location and the current applying level when modes parameter sensitivity analysis is used in the above fields.
