摘要
介绍计算机随机模拟固体火箭发动机内弹道平衡段压力的方法。文中视各个性能参数为随机变量，使用ＥＤＦ检验等方法，确定了它们的统计分布。根据这些性能参数的统计分布，通过随机抽样，得到了它们的模拟样本值，进而计算出压力值。
his paper presents a new method of computer simulation of the pressure in equipollence zone of internal ballistics in solid rocket motor. Some characteric parameters of the solid motor are considered as random variables, their distribution functions are determined by the EDF (empirical distribution function) test method. According to the distribution functions of the characteristic parameters, random sampling are used to compute the simulation value of the pressure. Simulation results shows that the new method is valid.
