Size-dependent Elastic Instability of Gel CylinderWith Surface Stress

Huang Dianwu,Qiao Ling, Wang Shiji

Strategic Study of CAE 2007, Volume 9, Issue 4,   Pages 50-54

Abstract:

The elastic instability of a gel cylinder was researched with classical elastic theory. The non-classic boundary condition of the elastic instability has been educed by the energy functional variation analysis.  So a criterion equation of the elastic instability can be got. Through the analysis of the equation, it is found that the elastic instability is relevant to the radius, intrinsic scale and instable wavelength of the cylinder.

Effect of magneto rheological damper on tool vibration during hard turning

P. Sam PAUL, A. S. VARADARAJAN

Frontiers of Mechanical Engineering 2012, Volume 7, Issue 4,   Pages 410-416 doi: 10.1007/s11465-012-0341-4

Abstract:

Recently, the concept of hard turning has gained considerable attention in metal cutting as it can apparently replace the traditional process cycle of turning, heat treating, and finish grinding for assembly of hard wear resistant steel parts. The present investigation aims at developing a magneto rheological (MR) fluid damper for suppressing tool vibration and promoting better cutting performance during hard turning. The magneto rheological Fluid acts as a viscoelastic spring with non-linear vibration characteristics that are controlled by the composition of the magneto rheological fluid, the shape of the plunger and the electric parameters of the magnetizing field. Cutting experiments were conducted to arrive at a set of electrical, compositional and shape parameters that can suppress tool vibration and promote better cutting performance during turning of AISI 4340 steel of 46 HRC with minimal fluid application using hard metal insert with sculptured rake face. It was observed that the use of MR fluid damper reduces tool vibration and improves the cutting performance effectively. Also commercialization of this idea holds promise to the metal cutting industry.
