两栖武器水上射击后坐运动规律研究

Study of recoil force rule of amphibious weapon shooting on water

两栖武器水上射击时,全炮会在水上产生翻转、后移和下沉,后坐部分运动规律和后坐阻力规律与陆上射击时有很大差异。本文运用双重后座原理建立两栖武器水上射击时后坐部分和车体的动力学模型,并通过solidworks二次开发实时获取了水上射击时入水部分浮心和最大横截面积,从而对模型求解得出两栖武器水上射击的后坐运动和后坐阻力规律。结果表明,水上射击时后坐阻力以及后坐速度、后坐位移曲线较陆上射击时较为平缓,且最大后坐力明显下降。

Because of overturning,sinking and backward when the amphibious is being fired,the law of recoil movement and recoil forces is different from firing on land.This paper use double-recoil principle to establish an amphibious weapon firing dynamics model on water,and the solidworks system is being used to obtain the parameters of buoyancy center and largest cross-sectional area of amphibious weapon under water,at last we can obtained the law of recoil movement and recoil force of an amphibious weapon shooting on water by solving the model.The results show that the recoil resistance curve,recoil velocity curve and recoil displacement curve shooting on water are flatter than the ones on land,and the maximum recoil significantly decreased.
