共振振幅 meaning in English
resonance amplitude
Examples
- The vibration resistant performances of the parts that made o f pc are five times higher than that of casting iron , but weight is o ne third of it at the same volume . the thickness of the sfpc parts can be increased if the weight is equal . this would make natural fr equency and the amplitude of vibration reduced and improve the dy namic characteristics of a machine tool
用此种材料制造的部件，从减振性能来看，超过铸铁的5倍，相同体积下重量只有铸铁的1 3 ，在不增加其重量的情况下，壁厚可增大，使固有频率提高，共振振幅减小，静动刚度提高，改善了机床的动态性能。
