| Abstract: | This paper makes a static structure analysis and a dynamics modal analysis on a base structure through FEA software Pro/MECHANICA.Sensitivity analysis of total mass,max displacement,and modal frequency are carried out by setting four key dimension variables.At the end of this paper,an optimal analysis is carried out to calculate the exact dimension of the model. |
