新型舰炮系统时序化与随机性调度复合供弹方法

Design Method of New Naval Gun Based on Time-oriented Feeding and Random Scheduling

针对兼容发射的大口径舰炮弹种单一、射速低、更换弹种速度慢、持续作战能力差的突出问题,提出了时序化设计与随机性调度相结合的系统设计方法。依据该方法建立了系统机构的时间分配模型和系统多工作步时序机构的随机调度模型(制式弹平均供弹速率50发/min),并基于全系统工作时序和弹库系统Markov状态转移矩阵,对弹库系统机构进行了随机性调度下的补弹时序决策控制和全系统机、电和控制一体化性能仿真。仿真结果表明:优化后的系统机构在弹种更换条件下,连续10发的平均供弹速率超过35发/min,系统平均弹种更换工作时间为4.6 s;通过优化,弹药更换效率提高20%～30%.该方法为符合连续供、补弹性能要求的系统机构设计提供了参考。

A new method using a time-oriented design（TOD） and a random scheduling design（RSD） was proposed for some problems,such as low feeding rate,slow ammo-replacement velocity,of naval gun feeding system.A time allotment model of the system and a random scheduling model of multiple operating steps were established.The decision management and simulations of the whole system of the supplying work steps were carried out based on the RSD as well as Markov state transition matrix.It is shown from the integrated mechanical,electrical and control performance simulations that,under the condition of ammo replacement,the average feeding rate of continuous 10 rounds can exceed 35 rounds/min,the ammo replacement time can be less that 4.6 s,and the work efficiency of the optimized system is increased by 20%~30%.This method gives a reference to design the mechanism adapted to the continuously feeding and supplying demands.
