Study on Vibration Specification Analysis Procedure of Equipment with Isolator

A shelter mounted on a vehicle is equipped with an equipment rack, and a vibration-proof mount is implemented for isolation from the vehicle input vibration originating from the road surface condition. It is often different to select an appropriate vibration-proof mount at an early stage; in general, a different type of equipment rack is required for each weapons system, and various pieces of equipment are developed simultaneously during the design process. In addition, it is necessary to derive the vibration profile for the independent rack-mounting vibration-proof mount, and the vibration compatibility of commercial rack equipment. However, there is no process for the conversion of a selected vibration-proof mount to the external vibration profile presented in the Military standard. Therefore, in this study, a conversion profile is derived from a 1-degree-of-freedom vibration system and CAE vibration analysis, by separating the initial and completion stages of design. Moreover, an application method for use in the design stage of military equipment is suggested.
