摘　　要：The system dynamics model has been done. The contracting process of thecurved-surface of the rubber disc is analyzed carefully, which is the main research aspect of theelastodynamics in the system. The coupling equation of the 'elastic surface and fluid' is resolvedby inverse resolution method. The main characteristics of the system, for instance, thedeparting-tube velocity, with which a carrier is to depart a launch tube, are estimated throughresolving the simulation model of the system dynamics. The simulation is based on some knownparameters and the experiment outcome of the elasticity modulus of a special rubber. On the otherhand, the influences on the system characteristics accompanying with the changing of some systemparameters are discussed. Finally, the conclusions are given that the elastodynamic system has asuperior performance and that the system deserves to be developed further as a kind of launchdevice.The system dynamics model has been done.
