摘要
潜射内弹道性能试验具有小子样异总体的特点,通过对环境因子进行Monte Carlo估计,来获取潜射内弹道性能参数的统计规律以及不同状态性能的折算关系,这是基于环境因子仿真的性能折算评估方法。在此基础上提出了采用多元回归筛选环境因素的方法,全面分析了正态环境因子的影响因素,可进一步提高正态环境因子的估值精度;介绍了仿真评估软件系统的构成及仿真实验的设计方法,以速度环境因子估计为例,给出了主要环境因素的相关系数和环境因子的仿真估计结果,可有效进行非设计状态试验数据的转换、性能折算与评估。
Converting and evaluation methods for submarine-launched interior ballistic functional test are summarized： according non-design condition and small trial sample status. A method is put forward to convert the functional parameter of submarine-launched interior ballistic by developing a simulation software and estimating the environmental factor among normal samples with Monte-Carlo way. Evaluation method of interior ballistic functional parameter is also set up. Based on this method, the exact main environmental factors are defined by choosing multiple regression way, which can be used to comprehensive- ly analyze the influence factors of functional parameter , and to improve the estimation precision of normal environmental factors. The composition of simulation and estimation software system and the design method of simulation experiment are described in detail. The simulated and estimated results of condition factor among normal samples are given by taking the environmental factor of velocity for example.
