A brief overview of the development of shock testing machine is introduced firstly. Superiority andfeasibility ofapplying dual wave shock machinein shock test of shipboard equipment are discussed in detail.Outputwave characteristics of the dual waveshockmachines aresimulatednumerically by using of the mathematical models of positive and negative wave generating systems in the machines.Test conditions of thedual waveshock machine are analyzed and shock response spectrum of the shock machine with no-load are calculated. The numerical results show thatshock response spectrum of the dualwave shock machine locateswithin the allowableerror range, thus the output wave are correct and can be used in shock test in shipboard equipment.
