转管炮降低机心组导轨摩擦力研究

摘要

In order to reduce the minimal driving power ,to reduce the bolts velocity,the main roller relative to whole body,and the right-and-left rail and obliquity is researched. And the result indicates the maximal acceleration of cam ,the main roller relative to whole body is zero. It is well in non-altitude difference with bilateral angle. The optimization results shows that in the case of 9 000 rpm its driving power is 140 kw bellows to 31 kw and it is 22 % of its intrinsic ;its show in the case of 3 300 rpm 1 086.5 N to 10 000 rpm 9 779.3 N. And it shows in the no- transverse and yes-inclination 90.9%that yes- transverse and no- inclination.%为了使转管炮机心组消耗的驱动功率最小，对机心组速度、主滚轮相对机体位置、机心体左右导轨及倾角关系等对驱动功率的影响进行研究。表明最好选用机心组凸轮加速度最小，主滚轮相对机体质心位置等于零，最好用无横向位移以及有夹角的关系最好。优化结果表明：9000 rpm的射速，驱动功率由机心组加速度变化引起140 kw下降到31 kw，降到不足于原设计曲线的22%；射速为3300 rpm的主滚轮压力峰值参数化峰值1086.5 N，升高到10000 rpm的峰值9779.3 N。无横向以及有夹角降低压力有横向以及无夹角90.9%。
