摘要
在战场环境下,爆炸产生的烟雾会对激光引信的正常探测产生一定的干扰,成为制约激光引信正常使用的因素。选用瞬时点源模拟爆炸烟雾,基于高斯烟团模式进行建模仿真,得到烟雾浓度分布规律。改变相关参数,如源强、平均风速、扩散时间、释放高度等,得到参数改变对烟雾浓度分布的影响规律。源强影响烟雾浓度峰值的变化,平均风速和扩散时间对烟雾浓度的峰值、烟团位置以及烟团大小均有影响,释放高度的改变使不同观测点烟雾浓度呈抛物线变化。仿真结果对激光引信抗烟雾干扰提供一定的依据。
In the battlefield,the smoke caused by explosion would interfere with the detection of the fuze.It has become the factor which restrict normal use of laser fuze.Firstly,uses instantaneous point source to simulate explosion smoke.Then,models and simulates the distribution of smoke concentration based on Gaussian Puff Model.Finally,obtains the distribution of smoke concentration.Also,changes the relevant parameters,such as source strength,average wind speed,diffusion time,release height etc.,and learn about the impact of smoke concentration distribution caused by changing parameters.The source strength affects the peak value of the smoke concentration.The average wind speed and the diffusion time have the influence on the peak value of the smoke concentration,the position of the puff and the size of the puff.The change of the release height makes the smoke concentration at different points of view change like a parabolic.The conclusions above provide a basis for the anti-smoke interference of laser fuze.
