Abstract:

The techniques of missile is developing to a long-distance and shoot straight trend, the reasons of the centroid deviation were discussed by considering the dimension errors of modules at the step of design. Take one missile as an example, a warhead module was calculated by using the Worst Case method and Monte Carlo method. The results show that the results obtained by Worst Case method always have a small probability, and the results obtained by Monte Carlo method are more reliable, and are of normaldistribution in its tolerance based on the errors of most mechanical accessory.
