The Application of Subsection Simpson Integration on Artillery Firing Efficiency Simulation Modeling

Abstract:

The evaluation model of artillery firing efficiency is widely applied to firepower command&control and large-scale simulation, itis very important for improving precision and speed of calculation to enhance capability of firepower command&control and large-scale simulation. Two-dimensional subsection Simpson integration was introduced to evaluation the model, the analysis of two-dimensional subsection Simpson integration in theory showed that convergence speed of two-dimensional subsection Simpson integration enhance to O(h⁴). The simulation results indicate that, speed of two-dimensional subsection Simpson integration is higher 20 times than statistics experiment method, precision of two-dimensional subsection Simpson integration is a little higher than the typical numerical integration such as midpoint formula integration and statistical experiment method, but it can promotes precision by 10% than approximate computation method.
