分丸轮窗口飞出弹丸与抛丸叶片接触前后的运动分析

The Motion of Shots Flying Off the Window

在求解出了分丸轮窗口中弹丸飞出窗口时的速度及角度的基础上,推导出了分丸轮窗口中飞出的弹丸与抛丸叶片相碰撞时的具体位置;并对弹丸与抛丸叶片碰撞后的运动过程进行了分析,在此基础上提出了分丸轮窗口中飞出的弹丸将与抛丸叶片发生多次碰撞后飞出抛丸器。这是一种全新的观点,它为进一步提高抛丸叶片的使用寿命提供了重要的理论依据。

Basing on the velocity and the angle of shots flying off the windows, the concre/e position where the shots hit the vane has been deduced in this paper. The motion of shots after the collision has also been analyzedl -it is indicated that shots flying off the windows may hit the vane several times before they fly off the blast wheel. This is a new point which provided a new way to prolong the life of the vane.
