STUDY ON DYNAMICS CHARACTER-ISTICS OF AN ELASTODYNAMIC SYSTEM

摘要

The system dynamics model has been done. The contracting process of the curved-surface of the rubber disc is analyzed carefully, which is the main research aspect of the elastodynamics in the system. The coupling equation of the 'elastic surface and fluid' is resolved by inverse resolution method. The main characteristics of the system, for instance, the departing-tube velocity, with which a carrier is to depart a launch tube, are estimated through resolving the simulation model of the system dynamics. The simulation is based on some known parameters and the experiment outcome of the elasticity modulus of a special rubber. On the other hand, the influences on the system characteristics accompanying with the changing of some system parameters are discussed. Finally, the conclusions are given that the elastodynamic system has a superior performance and that the system deserves to be developed further as a kind of launch device.
