Modal Analysis of Mini-Small Object: Dental Drill

Abstract

In this paper, we analyze theoretically the use of correlation statistical properties in the random speckle field, in the non-contact recording of free response information of vibrating object, and in terms of time domain signals collected simultaneously at the multiple points, and we conduct system identification techniques in the frequency and time domains to identify the dynamic parameters. The vibration of the bending arm of the dental drill is measured and analyzed. The lower-order natural frequencies and mode shapes are obtained.

Experimental Study of the Static Modal Analysis on Milling Machine Tool

“…The natural frequencies and mode shapes depend on geometry, material properties and mass, support condition, and in-plane loads [1][2]. This agreed by previous researches [3][4][5]. By using the modal parameters to model the structure, they believed vibration problems caused by these resonances (modes) can be examined and understood.…”

Vibration Analysis of Flexible Multi-Body Drill String System by FSI

“…In traditional theory research, drill pipe was simplified as vibrating in x z 、 plane or , y z plane, and the vibrations in those two planes were identical. When setting boundary conditions, BHA was only allowed moving in one plane [14] . Actually, the drill string would engender the transverse vibration in any direction in the entire horizontal space.…”
