The equipment installed on ships must withstand impact loads. Equipment manufacturers produce prototypes for environmental testing and conduct vibration and impact tests to prove the environmental impact of the equipment. In this study, an elastic mount was selected to verify the structural safety of equipment applied to a warship. A vibration analysis was performed according to the vibration test method of MIL-STD-167-1A, and structural safety was confirmed. For the shock analysis, the impulse of a half sine wave with a duration of 20 ms at an input acceleration of 20 g and structural safety were confirmed. Vibration and impact analyses were performed for preliminary verification. Prototypes were manufactured, and environmental tests were conducted. Environmental testing confirmed no physical or functional damage, indicating that the product can be installed in ships.
