摘要：

Aiming at the incomplete combustion of the high-activity aluminum powder, the auxiliary method was used to effectively and accurately measure the combustion heat of high-activity aluminum, and the Monte Carlo method (MCM) was adopted to analyze the sources of uncertainty in the measurement. The distribution function of the relevant input quantity was determined by the principle of maximum information entropy, and the uncertainty transfer and output were carried out according to the measurement model. The influence of the number of simulations M on the calculation results was discussed. The results show that the high-activity aluminum powder is fully burned and presents high combustion efficiency, which means this method works excellently. When M is 100000, the measurement result of the heat of combustion is expressed as (28016 ± 570) J/g, and the relative uncertainty is 1. 0%. As the number of simulations M increases, the mean and standard deviation of the calculated results are closer to the theoretical calculated values. Compared with the GUM method, the MCM method is simpler and has fewer restrictions, which can avoid the derivation of the measurement model and the influences from the complexity of the measurement model. © 2023 China Ordnance Industry Corporation.
