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.

Stabilizing systems with Gyroscope are extensively used in various tracking devices for attaining the system's objective. Because of putting performance first in importance of system and focusing on specification of parts, designers are sometimes passing over the dynamic characteristics of system in vibrating condition. In this paper, we were dealing with unstable stabilizing control due to coincidence of stabilization platform natural frequency and that of Gyroscope used for sensing rate. For solving this problem, statics and dynamic test of silicon rubber with 3 different hardness were performed and similar stabilizing system was adopted to prove reasonability of rubber choice and static pre-strain.
