摘　　要：针对现有捕捉网弹存在的抛撒时机不可控、处置不灵活等问题,设计一种基于近感探测技术的张开可控式捕捉网弹;基于捕捉网绳承拉不承压的力学特点,建立了虑空气动力及重力影响下的捕捉网动力学模型,对其展开过程进行了仿真分析,并重点分析了地面风速对捕捉网展开效果的影响。结果表明:捕捉网在展开过程中展开面积先增大后减小,在年平均地面风速作用下,横风基本对捕捉网展开过程无影响;而相对于无风条件,顺风会使捕捉网有效工作距离增加23.0%,逆风使捕捉网有效作用距离减小20.9%。For the problems of the current capturing net projectile,such as uncontrollable throwing time and inflexible disposal,an open controllable capturing net projectile based on proximity detection technology is designed.Based on the mechanical characteristics of the net rope,a dynamic model of the capturing net is established considering aerodynamics and gravity,and its expanding process is simulated,and the influence of ground wind speed on the expansion effect of the capturing net is analyzed emphatically.The results show that the expanding area of the capturing net increases first and then decreases.On the influence of the annual average surface wind speed,the transverse wind basically has no effect on the expanding process of the capturing net.Compared to the windless conditions,the downwind increases the effective working distance of the capturing net by 23.0%,and the upwind reduces the effective working distance of the capturing net by 20.9%.
