Electronic components inside a projectile are subjected to high acceleration during launch. Failure of these components, affects the performance of the projectile. The objective of the research is to better understand how shocks are transmitted to electronic boards and to investigate ways to mitigate these shocks. A projectile model is created to mimic an actual projectile. As projectiles are usually composed of threaded components, the effect of the tightening preload torque on accelerations and frequencies of components on boards is discussed. Experimental results show that increasing the tightening preload torque can ensure that projectile behaves as a single body, which makes acceleration of a component on the board independent of tightening torque. Different methods of mounting the board in projectile are considered and ways of mitigating the acceleration on board is also discussed. The research also presents suggestions to duplicate experimental results using finite element methods.
