This paper deals with the theory of the movement of ball rotor in a fuze innon-inertial coordinated system and studies the differential equations of move-ment of ball rotor and the caculation of its starting time. The deviation of thecentre of ball rotor from the axis of projectile is discussed too. This paper maybe used as reference for fuze designer. This thesis contains four parts: 1. The analysis of movement of ball rotor in non-inertial system; 2. The study of the movement of ball rotor in non-inertial system of trans-lational motion; 3. The caculation of starting time; 4. The analysis of forces and movement that are produced when the centreof ball rotor deviates from the axis of projectile.

在小口径高炮、航炮、舰炮以及无座力炮弹所配用的引信中,球转子隔离机构应用相当广泛。它的主要优点是结构简单、容易制造、体积小,当弹丸转速较低时可以达到10M左右的炮口保险。如果和易熔合金保险机构联用,则可顺利解决远解间题。球转子是在离心力矩作用下转正的,因此它只用于旋转弹引信(其角速度ω≌9000~50000R.P.M)。球转子是一个值得重视的性能优良的隔离机构。关于球转子的理论分析是球转子作用可靠性问题和转正时间计算的理论基础,它将使我们掌握它的运动规律,用以指导我们的设计实践。本文应用非惯性坐标系统对球转子的运动进行理论分析,导出球转子运动微分方程组以及起动时间的计算公式。最后对球转子球心偏离弹轴的情况进行分析讨论。本文共分四个部分: 1.非惯性坐标系的球转子运动分析; 2.在平动非惯性坐标系中研究球转子的运动; 3.起动时间的计算; 4.球转子球心偏离弹轴时的受力与运动分析。

Its main advantages are simple in structure, easy to manufacture and small in volume. By means of this device we can get an arming delay if the rotational speed of projectiles is low (e. g. ω≈9000rpm).

The ball rotor, as an arming and safety device has found wide applications in the fuzes for small caliber projectiles used in antiaircraft, aircraft mounted and ship-based guns as well as for recoilless gun projectiles. Its main advantages are simple in structure, easy to manufacture and small in volume. By means of this device we can get an arming delay if the rotational speed of projectiles is low (e. g. ω≈9000rpm). The problem of arming delay may be easily solved if the ball rotor device is combined with a mechanism in which the safety part is made of meltable alloy (e. g. the fuze for small caliber antiaircraft guns). It is the centrifugal moment that causes the ball rotor to rotate, so that it is only used in fuzes for spin projectiles whose rotational speed is about 9000—50000rpm. The reliability of the function of the ball rotor and the calculations of its arming time are based on the theoretical analysis of its movement. This paper makes a theoretical analysis of the movement of the ball rotor by means of two non-inertial coordinated systems and introduces the differential equations of the movement of the ball rotor and the calculations of its starting time. Finaly, the deviation of the centre of the ball rotor from the axis of the projectiles is discussed.

在小口径高炮、航炮、舰炮以及无座力炮引信中,球转子隔离机构应用相当广泛。它的主要优点是:结构简单、易于制造、体积小;当弹丸转速较低时(例如ω≈9000rpm),应用此种机构可以得到炮口保险。如果与易熔合金保险机构联用(例如小高炮榴弹用引信)则可顺利解决炮口保险问题。球转子是在离心力矩作用下转正的,因此它只用于旋转弹引信,其角速度ω≈9000~50000rpm。球转子的作用可靠性问题、转正时间的计算问题都是以球转子的理论分析为依据的。本文应用两种非惯性坐标系对球转子的运动进行理论分析,导出球转子的运动微分方程组以及起动时间的计算公式。最后对球心偏离弹轴的更为复杂的情况进行分析讨论。

In this paper we make an approach to the nature of two characteristic terms Ge = -mαe and Gk = -mαk in the dynamical equation of a non-inertial system. The technical terms"inertia force" and "corialis force" used in the dynamics are not fit for the essense of Ge and Gk. After much discussion about the physical signification of Ge and Gk , we propose a new concept "the vecter with a force effect"(VFE)which indicates the real meaning of Ge and Gk more accurately than the so-called "inertia force".

本文对非惯性系原动力学基本方程式的特征项G_e=-ma_e和G_r=-ma实质进行了探讨.指出至今力学中把G_e和G_k称为“牵连惯性力”和“科氏惯性力”是不妥当的.在对G_e和G_k物理意义分析的基础上提出“只有力效果的矢量”,简称“力效矢”的新概念.这比“惯性力”的概念更能准确地表达G_e和G_k的物理实质.
