Model and Simulation of a Self-propelled Gun Chassis

The virtual prototype technology is also called mechanism system dynamic simulation technology, in which a digital model replaces a real prototype. In this paper, the virtual prototype of a self propelled gun is established through applying the virtual prototype technology to the design field of tracked vehicle and analyzing the configurations and the motion relations of the selfpropelled gun. Some mechanical models used in the virtual prototype are discussed. Finally, the driving process of the gun is simulated and analyzed.
