In this research, the isolator and the inner gimbal inside of typical EO/IR equipment were replaced with a spring stabilizer. This Spring stabilizer system revealed an internal platform capable of external vibration damping and 6-DOF driving. This system was designed based on machined springs and spring modules of the spring stabilizer, structure, and other fixture. Through modal vibration analysis, suitable material for the spring was determined. Structural stability of the spring stabilization device was determined through random vibration analysis.
