Simulation for Langlie Method Test of Fuze Arming Distance

WEN Quan,WANG Yu-shi(School of Mechanical Engineering,Nanjing University of Science and Technology,Nanjing 210094,Jiangsu,China)  
In mathematically statistical test methods that were used to get arming distance of fuze,Langlie method was applied more and more wider because it only uses a few samples.Langlie method test of fuze arming distance was simulated and calculated with Mote-Carlo method.Its result shows that the estimate of 50% response level of stimulus for arming distance can be got through using a little sample,but the error and scatter to estimate of variance for arming distance is large;the amending coefficient to estimate of variance can be got through simulating and calculating,but it is useless to the certain single test;this means that the estimated arming distance of fuze by the langlie method test has large error,and the maximum of arming distance becomes shorter and the minimum of that becomes longer without amending.
