Present mechanical design techniques (including fatigue design) dependon "factor of safety" to compensate for limited knowledge of materials andloads. The resulting design is probably considerably heavier than necessary.An approach to reliability is one method of light designs which is importantin varied fields, as design of some structures and components of aerospace,aeroplane and automobile technology, etc.. Since many of the parameters taking places in fatigue design as load,material strength and geometric properties of component, are statistical innature. Distributions are assumed to be normal and to vary independentely.The curves of strength and stresse distribution will form an overlap areawhich characterizes the fact that stress has exceeded strength and so thecomponent will be fail. Introducing the algebra of normal functions and the Goodman's diagrammodified by statistical method, the approach of reliability in fatigue designwill be given.

目前的机械设计方法(包括疲劳设计)是依靠“安全系数”来补偿对材料及载荷知识的不足,所得的设计可能比必需的要笨重得多。可靠性设计是减轻重量的一种设计方法,这种设计可应用于不同的领域中,如航天、航空和汽车等的某种结构及零件的设计。 由于在疲劳设计中的很多参数,如载荷、材料强度和零件的几何尺寸,都是具有统计特性的,假设这些参数都为正态分布并彼此独立的。强度及应力两个分布曲线存在有一个重叠面积,它表征了应力超过强度或零件要破坏的情况。 引入正态分布函数的代数及用统计法修正的Goodman图线,作出了疲劳强度的可靠性设计。

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...

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。
