On the basis of the author's former paper, in this paper the forced vibrations of rectangular orthotropic plates taking into account the shear deformation and rotatory inertia are discussed. At first, the normal modes of free vibrations are obtained. Next, using the E. C. assumption about the internal frietion and the complex variable method, the forced vibrations of rectangular plates with simply supported edges under various harmonic disturbances are solved. At last, as an example, the result is applied to...

The flexible damped support-rotor systems have, in the recent years, been gradually adopted in the design of aeroengines instead of the earlyrigid support-rotor systems. The purposes of using the flexible damped support structure are to vary resonant frequency and diminish response of vibration.To this end, the parameters of the dynamic characteristics must provide a suitable conjugation between the support and the rotor. That will inevitably entail a great number of computations and tests. The mechanical impedance method is a very simple and effective means of predetermining the critical speed and the vibration damping characteristics of the rotor-flexible damped support system.This paper analyses the impedance method for the critical speed of the rotor support systems as studied abroad and presents a subsystem impedance method with supposed impedance values at the coupling points of the rotor and the support. It effectively resolves the problem of predetermining the critical speed of the rotor system with double flexible damped supports.This paper also presents a simple way to determine the resonant frequency by means of the curves.

近二十年来,航空燃气涡轮发动机转子系统的弹性支承设计已逐步取代了早期的刚性支承设计。采用弹性阻尼支承结构的目的是调频与减振。为此,支承与转子的动态特性参数必须有良好的匹配,这就需要进行大量的计算与试验。机械阻抗分析法是预示转子—弹性阻尼支承系统的临界转速及其减振特性的简便有效的手段。 本文在国外关于转子支承系统临界转速的阻抗分析法的基础上,提出转子在与支座交联点上假设阻抗的子系统阻抗分析法,有效地解决双弹性阻尼支承的转子系统临界转速的预示。 给出一系列交联点上的假设阻抗值,由转子子系统的频率方程求得转子子系统相应的共振频率特性。弹性阻尼支座的位移阻抗特性可由计算或试验确定。在平面直角座标系中,转子子系统与支座子系统的特性曲线交点,便是整个系统的共振频率。文中还提出了由曲线图确定共振频率的简易方法。

Existing techniques for predicting sound TL of double panel partitions are based on the assumption that the mechanical connection of the stud is a rigid sound bridge, but they provide unrealistic estimates of the TL in the ease of metal stud partitions. The TL of the latter is significantly improved at mid and higher frequencies owing to the lateral resilient effect of the stud itself. A modified expression for predicting the TL of metal stud partition is thus given in this paper, which is in good agreement...

现有估计双层轻板隔墙隔声量的方法是从刚性声桥出发的,它对钢龙骨隔墙并不适用。后者由于龙骨本身具有侧向弹性作用而使中高频的隔声量有所提高。本文提出了估计钢龙骨轻板隔墙隔声量的表达式,并与实验结果符合良好。本文还对龙骨两侧附加弹性阻尼垫条对隔声改善作用进行了讨论。对这样一种构造较为复杂的隔墙现在也能用一组简单表达式来确切地预计其隔声量。
