三维装药几何通用型面模拟计算法

GENERALIZED SHAPE SIMULATION METHOD OF THREE DIMENSIONAL GRAIN GEOMETRY

本文对目前广泛采用的“坐标药柱通用模拟计算法”作了有益的改进.模拟装药表面的各基本几何型面更加灵活通用,数学过程也变得简单方便.可对各种类型的三维装药进行快速、准确的计算.通过对某翼柱型装药的几何计算,获得了令人满意的结果.

The 'Generalied Coordinate Grain Simulation Method' which has been used to design solid propellant grain widely is improved in this paper.The basic geometry shapes used to simulate the surface of grain becomes more reliable and general.The mathematical treatment also becomes more simple and convenient. This method can be applied to the geometry calculation of different types of three dimensional grains quickly and accurately. The use of the method in a three dimensional slotted tube grain has demonstrated that the results are satisfactory.
