【摘要】 本文利用自己研制的双向激振器与常规通用仪器相配合,对一台外圆磨床进行了双向激振测试,求出了试验磨床的有效动柔度曲线,从而为激振试验测试外圆磨床结构动态性能提供了新方法和新装置。更多还原

【Abstract】 The operating principle and construction of a specially designed double-directional electromagnetic activator for dynamic testing of a matrix cylindrical grinder are described. Experimental determination of effective dynamic flexibility was carried out using the activator together with conventional instruments. During test, the activator should be supported on a foundation separated from that of the grinder.更多还原
