为了研究比药量对大剂量森林灭火弹爆轰特性产生的影响,利用仿真软件对所建立的弹体模型进行爆炸仿真。根据仿真结果,建立表征比药量影响的水剂爆轰特性方程,并选取适当比药量范围的灭火弹进行了静爆实验,绘出比药量与有效灭火半径之间的关系曲线,确定了最佳比药量范围。同时利用特性方程计算样弹的有效灭火半径,与实验结果比较得两者存在一定误差,为了使公式更加准确引入了修正系数对公式进行了修正。
In order to study the effect of specific dose on the detonation characteristics of high-dose forest fire-extinguishing shells, the simulation model was established to simulate the explosion of the projectile model. According to the simulation results, the detonation characteristic equation which characterizes the influence of the specific dosage is established, and the static explosion experiment is carried out by selecting the fire extinguishing bomb with the proper specific dosage range. The relation curve between the specific dosage and the effective fire extinguishing radius is drawn, The best than the dose range. At the same time, the characteristic fire equation is used to calculate the effective fire extinguishing radius of the sample projectile. Compared with the experimental results, there is a certain error between the two. In order to make the formula more accurate, a correction coefficient is introduced to correct the formula.
