Abstract: 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 comprehensively 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.
