| Abstract: |
| To propose a quantitative method for safety assessment of charge construction under the condition of droping/impact accident. Aiming at the problems of large uncertainty in the non-shock ignition of energetic components under the condition of the charge construction drop/impact, and lack of ignition criteria for engineering applications, a quantitative evaluation method based on mathematical statistics is adopted, and an evaluation system of “3 types tests and 1 method” is established. The methods and requirements of experimental design, quantitative evaluation method selection, and evaluation implementation are given, which can be used in engineering evaluation. Based on this method, a quantitative assessment of the drop safety of a certain charge construction is carried out, and the detonation threshold range under the specific constrains is obtained through exploration using standard tests. The safety value data of sample tests are obtained by designing and carrying out a configuration test which can envelope the overall response, and the quantitative evaluation result of safety is 0.999 99( with confidence level of 0.9). This method can realize the quantitative assessment of safety for weapon equipments and aerospace engines under drop/ impact conditions, but this method is only suitable for the situation where the charge construction has sufficient safety margin. |
