Abstract:

A method is derived to compute the force signature of a body impacting on a linear elastic structure. The time history of the impacting force is reconstructed from the response to impulse and response to the force at various points on the structure. The method is quite general and is applicable to any linear structure. The method is tested on a two degree of freedom system with various applied forces and reconstructs the forces very accurately.
