DESIGN AND ANALYSIS OF A MECHANICAL SYSTEM FOR DEPLOYMENT OF GOODS

ABSTRACT This paper aims at design a mechanized mechanical system which enables to stop and drop object at regular interval. The development of this mechanized system has several advantages, one of the applications is to drop objects such as food packets, cloths…etc from the helicopter during cyclone. This paper gives full details of design of the mechanized system along with structural analysis. This structure consists of two worm gear drives and L-shaped arms mechanism. This paper also carries out structural ansys of worm gear drive to stop lodes for while and then drop. The analysis is carried out using ansys soft ware. The structural ansys enables to modify the initial design of mechanism to meet the requirement of varies drooping intervals of goods such as food items, and cloths bags during cyclone. Sensitive analysis is also carried out to bring out the influence of design parameters on stress and natural frequency of worm gear mechanisms.
