This paper reviews a finite element model of a wire rope isolator (WRI) via an experimental comparison test. A local operation panel (LOP) mounted on a WRI is modeled using a finite element method. Mode analyses and harmonic analyses are conducted while varying of the thickness of the rope for the WRI. A feasible WRI can be selected considering the reduction of the vibration and the total weight of the LOP system.

Antenna equipment is transported being assembled to moving equipment and often subjected to vibration and shock excitation during transportation. In these circumstances, structural safety of antenna equipment must be secured. Wire rope isolators are assembled between moving equipment and antenna equipment to reduce the level of vibration and shock. In this paper, a isolator that are suitable to the system is selected and dynamic characteristics analysis of driving on antenna equipment is conducted using real system and the result is compared with response analysis. Also modal test of array-antenna pack-assembly is conducted and structural safety of that is secured by reinforcing its structure.
