本文在试验分析的基础上,建立了子弹的柔性飘带空气阻尼特性的数学模型,并导出了相应的空气阻尼力矩系数的计算公式。算例表明,计算结果与试验值符合较好。
Based on the experimental analysis, the mathematical model of the air damping characteristics of the flexible flaps of bullets is established and the formulas for calculating the air damping torque coefficients are deduced. The example shows that the calculated result is in good agreement with the experimental value.
