Probabilistic Study on Thermal Sensitivity of Energetic Material
The Frank-Kamenetskii parameter δ was supposed as stochastic variable of normal distribution, by the application of the probability density formula of monotone function, the thermal sensitivity probability density function of energetic material was worked out. On this basic, the thermal safety degree of energetic material was calculated. The result show that: the thermal sensitivity of energetic material is not normal distribution, but it is a kind of new probability density function which is decided by geometric factors: the characteristic measurement of reactant: a and geometric shape of reactant and chemical factors: quantity of reaction heat: Q; activation energy: E; density: p; frequency factor: A; thermal conductivity: A. The calculation show that: the value of safety degree is decided by the sensitivity distribution function.
