一种组件化仿真模型(SCM-1)及其实现

Simulation Component Models and Implementation

火箭飞行仿真系统是一种复杂大系统;为降低系统开发的复杂度,相关专业仿真模型应具有较高水平的可重用性以及较低水平的建模复杂度,并且遵照统一的建模规范,提出了一种新的仿真组件模型(SCM-1),论述了该模型的输入/输出接口、控制接口和功能接口组成形式,设计了基于XML的模型描述规则和C语言标准代码框架,在此基础上研究了一系列该模型的通用支持工具,最后给出了某弹道模型的实例,实践表明该仿真模型建模规范能够有效提高火箭飞行仿真系统的效费比。

Rocket simulation system is a complex giant system. To reduce the complexity of system development, simulation model need have high reusability, low modeling complexity, and conform to a unified modeling specification, we proposed a new simulation component model, exposed the instances of I/O interface, control interface and function interface. Designed a description based on XML and a frame- work based on standard C language. Based on the modeling specification, we researched on the general support tools for this kind of model and finally project a sort of Trajectory model. The development experiment show the modeling specification can make simulation system cost effectiveness.
