【摘要】 火炮身管的性能影响弹道性能,并最终影响作战效能,以物元分析理论为手段,对火炮的身管性能进行了综合评价。在身管性能的物元评价模型中,评价指标的选取是一项重要的基础工作,对火炮身管性能进行了认真分析,提出了评价身管性能的指标(初速,膛压,射击精度和有无早炸、瞎火及近弹现象),进一步确定了这些指标对3个评价等级的经典域和节域,通过计算待评物元对评价等级的关联度,来评价身管性能。通过对某型舰炮身管性能的实例计算验证了模型的正确性。更多还原

【Abstract】 Capabilities of gun barrel have influence on trajectory performances, and ultimately affect ope-rational effectiveness. By means of the knowledge of matter element analysis, comprehensive evaluation of gun barrel capabilities was performed. In the matter element evaluation model of gun barrel, establishment of evaluation indexes was an important and basic work. The capabilities of gun barrel were seriously analyzed, and the indexes of comprehensive evaluation (muzzle velocity, bore pressure, firing accuracy, with or without the existence of early burst, misfire, and short round) were proposed and defined, then the classical extent and nodal extent of 3 grades of evaluation were established, and the relevancy degree of matter element under evaluation was calculated to evaluate gun barrel capabilities. The correctness of the model has been verified by use of calculation for a certain example of a naval gun barrel performance.更多还原
