我校学报1979年第2期中《不平衡响应与共振转速区》一文,即文献,提出了两个概念,一为共振转速区,二为条件共振转速。这使我回忆起以前曾和室内同志们讨论过的几种定义和处理办法,在这里简略回顾一下,并说明所以不采用它们的一些考虑和实践。1.以某一、二个特定截面的振幅达极大作为共振判据。这是最初的想法。因为这样做最简单,尤其当特定截面取为轴承所在截面,与实际监控、检验取的截面一致,在直接经验中是很容易接受的、似乎作为一种工程处理未尚不可。但终究存在着由此导致共振频率随主观上如何选特定截面而改变的结果。2.一、二个截面不好,我就考虑如何使全部截面的振动信息都起作用。最简单的办法
Our journal “No. 2, 1979” in the “unbalanced response and resonance speed zone,” a text, that is, literature, put forward two concepts, one for the resonance speed zone, the second is the condition of resonant speed. This reminds me of several definitions and solutions I had discussed with my comrades before, briefly reviewing them here and explaining that some of their considerations and practices are not used. 1. To a certain, two specific cross-section of the amplitude of the maximum as a resonance criterion. This is the original idea. Because this is the simplest to do, it is straightforward to accept that a particular cross-section is the section where the bearing is located, consistent with the actual monitoring and inspection cross section, and seems to be acceptable as an engineering process. Ultimately, however, there is the result that the resonance frequency changes subjectively depending on the specific cross-section. One or two cross-sections are not good, I consider how to make all the cross-section vibration information work. The easiest way
