Design and Evaluation of Shock Isolation of Trailer Mounted Electronic Equipments

Abstract

In the design of Trailers and flatbed trucks for transportation of mobile electronic equipments for military applications, shock levels reaching the equipment are to be limited to a specified value, over varied input shock levels encountered from cross country terrains. To achieve this, the suspension system of the vehicle needs a scientific design technique.

Starting from the basic design principles, this paper brings out a simplified design approach for selecting a suitable suspension system. The evaluation measurements done on such trailers in field trails confirm the practical utility of the simplified approach. The peak and average accelerations measured at various points in the trailer are presented in the paper. This paper presents a mobility configuration arrived at in supply of mili tary grade system by Bharat Electronics, India.
