摘要：
Proper pretest planning is a vital component of any successful CNC machine tools'vibration test. An extremely important part of the pretest exercise is the placement of sensors.In general, the placement of sensors of CNC is uniform distribution, which depends on test engineer's experience. This paper considers the problem of locating sensors on the CNC machine tools with the aim of maximizing the data information so that structural dynamic behaviorof CNC machine tools can be fully characterized. We present a new technique,based upon Effective Independence (Ell) and Shannon's Sampling Theorem,that can meet test accuracy requirements and the visualization of the mode shapes. The technique is applied on XHK5140 CNC machine tool successfully.
