A mechanical impedence method is described to predict the natural frequences of elastic beam under the condition of dynamic supporting with the example of helicopter tail rptor. When two elastic components are connected at one point, it is sufficient to know the undamped impedence data of two connected components at the junction point ( determined by measurement or calculation) . It follows that the natural frequences of complete system not only reflect the natural frequences of elastic beam ( tail rotor...

A mechanical impedence method is described to predict the natural frequences of elastic beam under the condition of dynamic supporting with the example of helicopter tail rptor. When two elastic components are connected at one point, it is sufficient to know the undamped impedence data of two connected components at the junction point ( determined by measurement or calculation) . It follows that the natural frequences of complete system not only reflect the natural frequences of elastic beam ( tail rotor ) under the condition of the real dynamic supporting, but also indicate the influence of the components on supporting base.

本文以直升飞机尾桨为例,介绍了确定弹性梁在动态支承条件下固有频率的一种机械阻抗方法。在两个弹性部件呈点交联的情况,只要求两个部件在交联点的无阻尼阻抗数据(可由阻抗测试或计算确定)。由此得到的整个系统的固有频率,既包含了弹性梁(尾桨)在真实动态支承条件下的固有频率,又揭示了该部件对支承基础的反作用。

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 dynamics of a elastically supported, dynamically tuned gyroscope under idealconditions is discussed in this paper. A new presentation of the theory of this gyroscopeis given, which helps obtain the principal results more simply, since the superfluousdeductive process, which appears so often in the existing literatures, is omitted. It alsohelps understand the physical essence of various mechanical phenomena of a tunedgyroscope.
