Study for verification of Analysis modeling with investigating dynamic characteristic about 2 axies gimbals system

2 axis gimbals systems are extensively used in various tracking devices for attaining the system's objective. Designers are sometimes passing over the dynamic characteristics of system in vibrating condition In this paper, 2 axis gimbals systems including interface elements is modeled with finite elements. To verify this model, the finite element model is refined by using the experimental model data. The refined model is simulated with I-DEAS and MSC.NATRAN's FRF(Frequency response Function) and RRA(Random vibration Response Analysis) function to get dynamic characteristics of 2 axis gimbals system.
