GLOBAL DYNAMICS SIMULATION OF MULTIBODY SYSTEMS WITH VARIABLE TOPOLOGY

New concepts, a basic system and a current system for a multibody system with variable topology, are proposed for the global dynamics simulation of the complex mechanical systems By use of technology of activation of passive constraints, the exchange of topologies of a system is automatically completed in the simulation process The software DAMB, developed by the authors is extended to simulate the whole dynamic process of a system An example, the simulation of launching of a rocket gun system, is giv...
