| Abstract: | Through the application of finite element analysis,the key sizes of a front mask of quick opening closure with locked hoop were optimized,the safety probability of it by applying Monte Carlo calculating method was determined,so finally the failure probability was gotten.By optimization,the volume decreases by 34.7% with a failure probability only 0.007 2%,it can be operated easily and safely. |
