摘要
为了提高多管火箭的射击密集度,利用多体系统传递矩阵法建立了某多管火箭发射动力学模型和射击密集度仿真系统,用多管火箭固有振动特性的模态试验结果验证了相关仿真结果,利用仿真系统对不同发射环境下振动特性、动力响应和密集度进行仿真研究,并对射序和射击间隔对密集度的影响进行仿真研究,得到提高多管火箭密集度发射的最佳射序和射击间隔,研发了小型化的多管火箭可变射序和射击间隔发火装置,可实现最佳射序和射击间隔高密集度发射,在某次密集度试验中,利用该发射技术使某多管火箭射击密集度提高20%以上。
To improve firing dispersion of Multiple Launch Rocket System（MLRS）,the launching dynamic model of MLRS and the simulation system of firing dispersion of MLRS were established by using transfer matrix method of multibody system.The simulation results were validated by the modal test results of the vibration characteristic for MLRS.The vibration characteristic,dynamics response and firing dispersion of MLRS under different firing environments were simulated,and the influencs of firing dispersion of MLRS with different firing orders and firing intervals was researched,the optimal firing orders and firing intervals for improving firing dispersion of MLRS was obtained.A smaller firing device with variable firing orders and intervals for MLRS were designed and actualized,and the firing technology with higher firing dispersion of MLRS by the optimal firing orders and firing intervals could be realized.In some firing dispersion test,the firing dispersion of MLRS is improved over twenty percent by using the firing technology.
