Design of High Intensity Impact Simulation Test Facility

Space vehicles will be subjected to high intensity impact during different stages of its course of application. High intensity explosive devices will be used in these vehicles for serving various functions like stage separation. These explosive devices will be attached to the space vehicles and once they are initiated high intensity impact will get produced due to explosion which will get transmitted to space vehicles. Sub systems of these space vehicles will be designed against this high impact loads. However design adequacy and functional working of these subsystems needs to be ensured before they become passengers of the space vehicles. It is a general practice to do the test by employing real environment explosive devices. But this means of testing calls for risk associated with explosion. Apart from this it also involves cost implication. Hence great need exists for alternative means which provides safe testing. The objective of this work is to design high intensity impact simulation test facility using mechanical means. It is proposed to drop hammer on the fixture and there by simulate the impact to the UUT mounted on the fixture. Initially hammer will be dropped due to gravity from certain height in order to gain the velocity and there by impact. Impact energy will be proportional to velocity and in turn depends on drop height. All the subsystems of the proposed design will be designed and accordingly their respective dimensions will be worked out.
