Study on the Relations between the Structural Parameters and the Dynamics Properties
The general rule that the modal parameters of linear system change with the structural parameters was discussed. The calculational method of the change of modal parameters was given on the basis of the current modal parameters and the change pattern variation of structural parameters. An example indicated that this method can greatly save computational time than repeated modal analysis. Withal, the qualitative conclusions of the change of modal parameters can be expediently gained. These results are important to amelioration and optimization design of systems.
