一个装满叶片的轮盘(Bladed—disc,以后简称“叶轮”)组成的汽轮机级,可能按其许多自然方式中的任何一种方式振动。如想做到避免汽轮机振动,重要的事情是了解这些方式中的那一种可能在运转的汽轮机中被激发而引起叶片损坏。对于通用电气公司(G.E.C.)所制汽轮机,已通过多年仔细研究所有曾发生过的叶片损坏而获得此资料。本文作者考虑到,解释从这样调研中所得资料尚有困难,故在此对不同形式振动所致的运行损坏予以具体说明。振动造成的叶片损坏,现在几乎只限于小型及陈旧的汽轮机。文中强调对于这些汽轮机中发生的任何叶片损坏应予以彻查。 A turbine stage consisting of a bladed disc (hereinafter referred to simply as “impeller”) may vibrate in any of its many natural ways. If you want to be able to avoid turbine vibrations, it is important to understand that one of these approaches may be triggered in the running turbine to cause blade damage. For G.E.C. turbines, this information has been obtained by years of careful study of all vane damage that has occurred. The author of the paper considers that there is still some difficulty in explaining the data obtained from such investigations. Therefore, the operational damage caused by different forms of vibration is described here in detail. Vane damage caused by vibrations, and now almost limited to small and old steam turbine. The paper stresses that any damage to the blades in these turbines should be thoroughly investigated.
