摘　　要：为减小某型线膛火炮身管膛线起始部和炮口部导转侧力,编制了涵盖等齐、渐速、混合三种膛线类型以及常见膛线曲线的膛线导转侧力通用计算程序,构建了合理的目标函数,以膛线类型以及膛线曲线参数为自变量,分析了各参数变化对目标函数的影响,并用非线性优化算法、模拟退火算法和遗传算法对目标函数进行了优化,为该型火炮选取了合适的膛线类型和膛线曲线。研究也发现目前文献中推荐的正弦膛线曲线是不正确的。To decrease certain rifled gun's leading slide force in rifle beginning part and muzzle part,a generalized calculation program is programmed for the universal leading slide force calculation for ribbed rifling,gain rifling,mixed rifling and including common rifle curves.Reasonable goal function is built,rifling type and rifling curve parameters are selected as variables.The variables'influence on goal function is analyzed;the goal function is optimized using nonlinear optimization algorithm,simulated annealing algorithm and genetic algorithm;so the gun’s proper rifling type and rifling curve are obtained.In addition,the sine rifle curve recommended in some books is proved improper.
