Design and Simulation of Missile-borne Measuring Device Shell

Missile-borne measuring device needs to be installed in the missile body. When projectiles running in trajectory, they are in a high temperature, high pressure, high g value of the overload conditions, therefore whether reasonable of the mechanical shell design or not has important implications for the entire test system anti-overloading performance. According to the test environment characteristics and compatibility with the principles of the PCB, Mechanical protection shell takes cylindrical structure. According to strength theory, calculates the design parameters of the cylinder and make structure design, strength analysis, limited simulation calculation. Simulation results show that, the strength of missile-borne measuring device designed meet the requirements of gun in high chamber pressure when fired.
