| Abstract: | Aiming at the problem that the accuracy is difficult to improve in the current mortar exterior ballistic simulation research, a computing method was proposed. Computing method was regarded as research object and the conventional exterior ballistic model was optimized and refined to build a more accurate mortar exterior ballistic model. The explicit and implicit algorithm in the linear multistep algorithms were combined to design a practical prediction correction algorithm. This algorithm was applied to calculate ballistic model, and the results were compared with the firing table. The results show that compared with the conventional Runge Kutta algorithm and the linear multistep algorithm, the prediction correction algorithm is more accurate and timesaving. The research results directly reveal the advantages and disadvantages of several trajectory calculation algorithm, which can effectively guide the selection of algorithms for ballistic model calculation. |
