为了解决弹道仿真中弹道解算和解算结果实时动态表现两个关键问题,将面向对象与Petri网相结合应用于弹道仿真建模和仿真过程管理,从而较好的解决了弹道计算问题;运用Vega技术对弹道解算结果进行可视化显示,使得弹道仿真计算与结果动态展现有机结合。仿真结果表明,所采用对象Petri网和可视化技术有效的解决了弹道仿真中弹道解算和数据实时动态表现两个关键问题,对其它动态复杂系统的仿真也具有很好的借鉴作用。

In order to solve the problems of trajectory calculation and real-time dynamicly showing the results in trajectory simulation, a method of combination object-oriented with Petri net is used in simulaion modeling and simulation management of trajectory simulation, that effectively solves the prolem of trajectory calculation; the method of using the Vega visualization technology to show the trajectory data lets the results and visual display combinate well. The simulation results show that the object-oriented Petri net and visualization technology proposed here well solve the problems of trajectory calculation and visual display of data. And this also has a good reference for the simulation of other dynamic complex systems.
