Abstract

The current sensitivity probability density function of energetic materials was deduced based on Frank-Kamenetskii parameter and resistance supposing as stochastic variable of normal distribution, by the application of the probability density formula of function in two random variables. The calculation method of current fire reliability of energetic materials was worked out too. Results show that the probability distribution of current sensitivity of energetic materials is not a simple mathematical function, but a very complicated function which is influenced by physical and chemical parameters of hot wire such as resistance, mass and specific heat, and influenced by physical and chemical parameters of energetic materials such as specific heat, density, reaction heat, frequency factor, thermal conductivity and activation energy.
