Abstract

Component modal Synthesis method used in natural characteristic analysis is introduced in this paper. The principle of component modal synthesis method is described. Based on this principle, the sub-structure of tracking frame of electro-optical theodolite is divided and FEM is set up. The natural frequency of tracking frame of electro-optical theodolite is calculated in the end. The results showed the component modal synthesis method has the advantage of less calculation load, higher accuracy, worth to popularize and application foreground.
