Abstract
An electronic slave hammer is used to improve the performance of impact testing. The electronic programmer as well as the power electronic circuits are presented. The geometry of the piston tip of the hammer and on duration of contact between the tip and the structure is discussed. It is shown that the polyreference method of modal analysis is applicable to impact testing with multiple slave hammers.
