摘要: 以SolidWorks的二次开发接口为基础,用Visual Basic作为开发工具,在SolidWorks环境下通过调用内置的API函数,自动完成嵌金属丝药柱的参数化建模.程序同时通过调用API函数提取药柱实际参与的燃面面积,获得了嵌金属丝装药的燃面随肉厚的变化关系曲线,发展了一种更为简单准确的燃面计算方法,在此基础上,进行了内弹道性能的计算.计算结果跟试验结果相比表明,该计算方法准确且精度较高,跟试验结果吻合得很好,能够较好地模拟该类药型的燃烧过程,可以满足工程计算上的需要,并为同类型的复杂装药计算和设计提供了参考.

Abstract: A simpler and more accurate of propellant grain calculation which is based on SolidWorks API interface and Visual Basic has been developed for grain embedded metal wires. It can build parametrical model for grain embedded metal wires automatically and distill burning surface which occurs during burning process by SolidWorks API. As a result of the relation between burning surface and propellant thick, the interior ballistic performances can be simulated. The result shows that this calculation method is feasible and has a better precision. The calculation results are in good agreement with experiment results. It can also simulate the burning process of this type grain and be satisfied with actual engineering calculation. This software is a useful tool for difficult propellant grain calculation and propellant grain design with this type grain.
