The realization of model movement simulation in the training simulation system

The training simulation system is broadly used in the simulated training of real equipment or their working flow. The model´s movement simulation methods are the key and hard point in the system developing process. A movement simulation method is brought forward, that is, using matrix calculation to realize the corresponding coordinate transformation, using the topology relation among the parts (the sub-model) to realize the managing and model movement connection, so as to be able to use the same algorithm to complete movement simulation of each kind of models. Besides, the simulation method based on Decorator using in encapsulation of the model and the movement, can help reduce the complexity of programming and man-machine alternation. In the process of researching several simulation systems, this method is proved to be effective.
