Analysis of structural shock transmission

An analytic procedure is developed for evaluating response of a shock-loaded structure at some point, given only the response at some other point. A specific system is analyzed and the results compared with test data. Capability of the procedure to predict transmitted shock response is first demonstrated. An acceleration time history is then synthesized from a shock spectrum, as a sum of damped sinusoids, and used to predict shock response. Lastly, the response in the vicinity of the point of shock loading is predicted by numerical integration using a simplified model of the structure. The response so obtained is then used as input to predict transmitted shock response, demonstrating that response throughout a shock-loaded structure can be predicted without resorting to numerical simulation using a complete model.
