一种发射平台水面多弹分离过程的运动特性分析

水下运载器携带载荷至水面并快速完成分离是该类武器应用的重要环节。 以发射平台水面逐一发射多枚导弹的技术方案为背景,利用多刚体动力学模型对动基平台的水面多弹分离过程进行了数学建模。 在方案初步设计阶段,将三维模型进一步简化为一维模型,编写了可实现任意装填枚数的动基平台水面多弹分离过程动力学仿真软件;分析了平台出水速度、导弹装填枚数以及导弹发射间隔等参数对分离过程运动特性的影响;得到了发射平台水面发射多枚导弹的弹道变化规律。 计算结果具有一定的工程应用参考价值。

Motion Characteristics Analysis of Multi-projectile Separation Process on Water-surface from a Launching Platform

Underwater vehicles carrying loads to water surface and rapidly separating are important aspects of the application of such weapons. In the context of a technical scheme for launching multiple missiles in succession from launching water-surface platform, the process of multi-projectile separation from moving-based platform is mathematically modelled using multi-rigid-body dynamic model. In the preliminary design stage, the three-dimensional model is further simplified into one-dimensional model, and the dynamic simulation software for multi-projectile separation process on water-surface from moving-based platform with arbitrary number of missiles is compiled. The effects of platform water-exit speed, missile number and launch interval on the motion charac- teristics of separation process are analyzed, and the ballistic variation law of multiple missiles launched from a water-surface moving- based platform is obtained. The results have certain reference value for engineering application.
