This paper discusses the possibility and reality of adopting flexible rotors in marine steam turbines. Firstly, it deals with the advantages of using flexible rotors in marine steam turbines. In order to reducing the specific weight of the turbine equipment and improving the manoeuvreability, it is advisable to consider the adoption of flexible rotors in modern high speed steam turbines. In this paper, it explains that with high speed turbines, it is difficult to obtain a really rigid rotor due to the influence of the support rigidity. Though the first critical speed is designed to be 20~30% above the working speed, the actual first critical speed often falls down to a value below the working speed. By calculation, it can be proved that with a well-balanced rotor, the deflection of the rotor due to vibration when operating at a speed near or equal to the first critical speed for a fairly long period is very small, and we can expect the rotor working in a satisfactory manner. The paper also discusses the problem of self-excited vibration of a supercritical rotor. It explains that whirling effect due to the instability of oil film is the main opposition of the reliability of flexible rotor, and the oil whirling only appears when the working speed is at a value of twice the first critical speed. Therefore we must keep the working speed lower than that value. The paper also lists the region of the. critical speeds of flexible rotors. In conclusion, the author expresses his own opinions with regarding to the adoption of flexible rotors in high speed marine steam turbines, and claims that it will be advantageous and possible.

本文主要讨论舰船汽轮机采用柔性转子的可能性及现实性问题。文章首先说明了舰船汽轮机采用柔性转子的好处,着重说明了由于近年来舰用汽轮机的转速提高及设计点后移,为了进一步减轻重量及提高操纵性和机动性就要求采用柔性转子。文章论证了对高速汽轮机来说,由于支承刚性的影响,实际上很难得到刚性转子。尽管计算临界转速大于工作转速(20~30)%,而实际的临界转速仍然有可能落入工作转速以内。文中通过计算,证明了即使在临界转速下长期运转,只要转子平衡得好,振动挠度是很小的,转子工作亦是可靠的。文章还对超临界转子的自激动问题进行了讨论,并指出由于油膜不稳定性而引起的自激振动严重地影响柔性转子的工作可靠性。这种自激振动只是在工作转速大于二倍临界转速时才发生,因此必需使工作转速小于二倍临界转速。文中大致地给出了采用柔性转子时选取临界转速的范围。文章最后对舰船汽轮机采用柔性转子的可能性问题提出了意见,认为舰船高速汽轮机采用柔性转子是可能的,并且有一系列的好处。

The whirling arm unit has a 1 M. long whirling arm and has a working speed range of 0.01-3.50 M/sec. It is an improved model of an original one. Performance test showed that, all the technical requirements have been met. Some of the performance characteristics have exceeded requirements originally designed. The speed of swirl has been decreased from 10% (of arm speed) as generally obtained down to 0.7%, thus the total error of this unit is lower than 1%. This satisfactory result is obtained...

The whirling arm unit has a 1 M. long whirling arm and has a working speed range of 0.01-3.50 M/sec. It is an improved model of an original one. Performance test showed that, all the technical requirements have been met. Some of the performance characteristics have exceeded requirements originally designed. The speed of swirl has been decreased from 10% (of arm speed) as generally obtained down to 0.7%, thus the total error of this unit is lower than 1%. This satisfactory result is obtained through the introduction of damping screens, arubber seal and other means. The new whirling arm unit has a much higher calibration accuracy than the original one, and therefore may be used as a standard device for low air speed calibration of thermo-electric anemometers.

文中所述的旋臂机是一种基于相对运动原理,用来分度和校正低风速热电风速计的试验设备。它的臂长为1米,使用速度范围是0.01~3.50米/秒。经过调整和性能试验,结果表明:所有技术指标达到或超过了原设计要求,其中收效最力显著的是由于综合地采取了阻尼网和橡皮封等技术措施,使带动风速相对比值**从一般的10%左右减小到0.7%,从而使设备的总误差降低为±1%。因此该旋臂机有较高的准确度,可作为实验室低风速分度和校正的标准设备。
