Shock Simulator.
Abstract
A projectile ground shock simulator is described for simulating the force pulse on a projectile in testing for shock effect on the guidance system of the projectile. The simulator incorporates a liquid/solid material as an energy absorbing and storing spring for simulating the force pulse on the projectile. The projectile is positioned in a drop tube and impacted with a drop vehicle to simulate the force created during firing of the projectile. The drop vehicle is provided with the liquid/solid spring having a piston and cylinder on the impact face of the drop vehicle. The cylinder is filled with a liquid or solid polymer material having a high bulk modulus of compressibility which gives the spring volumetric stiffness. The spring thus duplicates the force pulse acting on a fired projectile and also allows for the drop vehicle to be reused. (Author)
