Design and Analysis of a Container with Vibration Shock Isolators during Transporting Small Rocket Motors

Rocket motors when transported in a container, there is a definite chance of development of vibrations due to the unevenness of the transportation path selected. This may damage the rocket motor inside. It is required to see that, the rocket components are not affected by vibrations during the transportation. This work attempts to design a suitable container with vibration isolators for absorbing the shock produced. Container is designed to carry 2 rocket motors each weighing 70 kg, made up of composite material, E-glass epoxy, and Isolators (generally made up of different materials) are placed symmetrically below the container. While transportation, the truck (the vehicle carrying container) is assumed to undergo an acceleration of 15 times of gravity, which is to be damped to less than 3 times of gravity, as 3*g is the maximum vibration the container can resist. Mathematical model based on Laplace Transformations is built and solved for checking the shock response with and without Vibration Isolators, for this MATLAB software is used. The 3D model of the container with Rockets is modeled in CATIA and the structural and Dynamic Analysis is performed using OPTISTRUCT of Hyper works.
