基于模块的运载火箭电气系统匹配验证仿真

Simulation for Avionics Validation of Launch Vehicle Based on SysML

为了缩短运载火箭的研制周期、降低研制成本,通过数字仿真实现对运载火箭电气系统的匹配验证显得尤为迫切;提出了一种基于模块的运载火箭电气系统匹配验证方法,采用SysML语言进行了函数编写和结构建模,实现了电气系统硬件与软件设备的匹配验证;通过与真实匹配试验中测试数据的对比,证实了该方法可以有效模拟并完成各电气系统的性能参数分析和接口匹配验证,具有一定的工程应用价值。

In order to reduce the research cycle and cost of launch vehicle,there is an increasing need to perform comprehensive system level Matching and Validation using modeling and simulation.An approach is implemented in SysML,which extends model-based Matching and Validation to electronics and software through functional and structural models.The Component models of electronics and software are developed which are validated by comparison with test results from actual equipment.This experiment demonstrated such an approach is possible.
