固体火箭发动机虚拟试验技术初探和应用

Study and Application of Solid Rocket Motor Virtual Test Technology

摘要:

为改进固体火箭发动机传统试验模式存在的资源瓶颈、试验性能难以预示等问题,在固体火箭发动机试验与测试领域引入虚拟试验技术,设计并开发了固体火箭发动机虚拟试验基础系统；阐述了固体火箭发动机试验模型、试车架模型的建模方法,利用均匀设计方法分析影响内弹道数据的主要因素权重,以修正虚拟试验内弹道数据；针对某型号固体火箭发动机进行虚拟验证,试验结果表明,虚拟试验基础系统在一定程度上具有与真实固体火箭发动机地面试验相似的流程和功能,通过修正虚拟试验内弹道数据,进一步降低了虚拟试验结果与真实试验结果间的误差,为深入开展固体火箭发动机虚拟试验技术研究奠定了基础。

Abstract:

In order to improve problem of resource bottleneck and test capability prediction knottiness in conventional solid rocket motor test mode. Introducing the virtual test technology into the realm of solid rocket motor test. Devised and established solid rocket motor virtual test foundation system. The modeling technology of solid rocket motor test model and test setting model were introduced, by analyzing rocker interior data impaction weight through uniform design method to modify virtual test interior data. According to some type solid rocket motor virtual test, the test results indicate circs that the system conforms the function of virtual test to actual solid rocket motor test on a certain extent. Revising virtual test data to further reduce error between virtual test results and actual test results. For investigating thoroughly solid rocket motor virtual test technology to lay a foundation.
