摘要

在某型火箭炮动力学模型基础上,采用二次编程技术,建立优化算法与动力学仿真的耦合。开展了相应发射情况的仿真优化分析,得到了最佳的发射时序及与之相匹配的变支撑刚度、阻尼,计算对比了优化前、后系统的振动特性,验证了优化结果的可行性。在此基础上,进一步优化分析了发射时间随机性对初始扰动的影响。研究方法及成果可为多管火箭炮系统的研制、改制提供理论支持。

Abstract

The coupled relationship of optimize algorithm and dynamic simulation was established based on launch dynamics simulation model of Multiple Launch Rocket System(MRLS).The launch dynamics simulation and optimization were performed,the best launch time sequence and corresponding support stiffness and damping were obtained and vibration performance was calculated also,all of these verified the valid of optimized parameters.Moreover,the influence of random launch time on initial perturbation was analyzed.The methods and conclusions can be used as a theoretical foundation for development and revise of new MRLS.
