敏捷供弹系统的扬弹机液压系统仿真

供弹速度是影响舰炮发射速度的重要因素,因此设计一套快速的供弹系统也是相当必要的。该文从敏捷供弹系统的组成出发,首先叙述了扬弹机的工作原理,而后建立了扬弹机的液压系统,对液压缸和蓄能器进行了具体的分析计算,从理论上证明了此方案的可行性。最后,利用Pro/e和Adam s软件对扬弹机及其液压系统进行建模仿真,进一步证实了此方案的正确性。对机构的驱动系统进行仿真研究,将提高虚拟样机的正确性和可靠性,为实际样机的成功打下更坚实的基础。

Mathematical modeling and analytical solution for stretching force of automatic feed mechanism

Load of an automatic feed mechanism is composed of the stretching force of feed belt at the entrance to lower flexible guidance and the friction force between feed belt and flexible guidance. A mathematical model for computing the load was presented. An optimization problem was formulated to determine the attitude of the flexible guidance based on the principle that the potential energy stored in the system was the minimum at the equilibrium. Then the friction force was obtained according to the attitude of guide leaves and the moving velocity of the feed belt and the friction factor. Consequently, the load of the automatic feed mechanism can be calculated. Finally, an example was given to compute the load when the horizontal and elevating firing angles of the automation were respectively 45° and 30°. The computing result can be a criterion to determine the designing parameters of automat.
