Study on Accuracy of Gough P.S and Guo Stress Formula in Calculating Propellant Bed Stress under Quasi-static Compaction
Ordnance Engineering College, 050003 Shijiazhuang, China
In order to verify Gough P.S and Guo stress formula and its accuracy in calculating propellant bed stress under quasi-static compaction, the paper adopted electronic universal testing machine to perform quasi-static compaction on propellant beds of two different diameters, and based on experimental data, the paper obtained stresses of the two beds in the process of compression. The paper used stress formula to calculate stresses of the two propellant beds respectively, based on the propellant bed feed and experimental configuration, and the results show that, during initial propellant compaction phase, the calculations are greater than experimental results, when it comes to certain compaction phase, the calculations of the formula are smaller than experimental results; the calculations of the formula are slightly smaller than experimental results.
