Shape Optimization And Weight Reduction Of Seat Structure For Wheeled Armoured Amphibious Combat Vehicle

Abstract

From last few decades increasing tension among country need armoured vehicle is tremendously increasing for battle field situations. Indian army need special purpose combat vehicle, which simultaneously run on land and float in water for situation like river crossing. For this purpose here need arises for wheeledarmoured amphibious combat vehicle. For successful amphibious operationweight is important factor in vehicle therefore emphasis is given on weight reduction. Seat structure is designed such way that weight reduction and shape optimization has been achieved with sufficient strength for comfort of solider. In present work 8 different combinations has been studied for different size shape and distance between structure member, 1st combination is manufactured and tested after that modal analysis,linear static FEA analysis has been done. For weight reduction first steel is used. Its result examined tested and after that aluminum alloy has been used. Best optimized combination has been suggested with different thickness of aluminum alloy and 75% weight reduction has been obtained with comfort for user.
