Parallel processing of animation showing and solving of multibody system dynamics
多体系统动力学求解与动画输出的并行处理

Parallel processing of animation showing and solving of multibody system dynam is investigated by using Local Area Net (LAN) technology in windows environment. Theory modeling and numerical simulation is reviewed first. Emphasis is focused on parallel processing of numerical solving and animation between computers in LAN, which is much different from traditional processing method in current engineering software. Modeling, numerical simulation, curve plotting and animation showing, and analysis is done step by step in traditional method, While numerical simulation and curve/animation showing can be done at the same time in different computers in LAN in this project. TCP/IP, which is widely used in computer network, is us to realize data exchange between different computers in LAN. And multi-thread technology used when two different functions should be completed at the same time in a single program. Client/Server programs are developed to make different computers communicate in LAN, where dynamcs simulation can be run in program on server and animation of system can be shown program on client. Example of cable simulation is presented to validate this technology, which the basis of simulation of multibody system dynamics.
