Application of Multilevel Optimization Algorithm in Artillery Integrated Design

The weapons and equipment are required to have high-mobilility，high-precision，long-range and lightweight in modern warfare. A noverall optimization design method is presented，in which the all aspects of performance of artillery are comprehensively considered. A parametric model of artillery is established，the sensitivity coefficients are calculated using the optimal Latin hypercube experimental design，and a large number of input-output data can be obtained at the same time. The weight values under different firing conditions and different evaluation indexes are calculated from the sensitivity coefficients，and the approximate functions are constructed based on input-output data.A multilevel optimization algorithm is set up based on these results above，and an optimal design scheme would be obtained after the algorithm convergence. The result shows that the evaluation indexes of the optimal design scheme are averagely increased by 22.27%，which is obviously improved compared with the initial design scheme.
