Numerical analysis of hydrodynamic process of circular-translational-moving polishing (CTMP)

ZHAI Wenjie, LIU Changxiong, LIANG Yingchun

Frontiers of Mechanical Engineering 2008, Volume 3, Issue 4,   Pages 441-448 doi: 10.1007/s11465-008-0074-6

Abstract: By keeping a pad moving relative to a wafer along a circular path without rotation, we developed a polishingtechnique called circular-translational-moving polishing (CTMP), which permits multidirectional polishingof the work piece and thus bears the advantage of isotropic polishing and a potential increase of materialThe reason for negative pressure in CTMP and its effect on polishing is discussed.pitch angles under different working conditions are obtained in terms of the applied load, moments, and polishing

Vibration analysis of a simply supported beam under moving mass based on moving finite element method

Zhuchao YE, Huaihai CHEN,

Frontiers of Mechanical Engineering 2009, Volume 4, Issue 4,   Pages 397-400 doi: 10.1007/s11465-009-0044-7

Abstract: In this paper, a moving finite element (MFE) method is proposed to perform the dynamic analysis of asimply supported beam for a moving mass (MM).The MFE method treats the moving mass as a moving part of the entire system, so that the transverse inertialeffects caused by the moving mass may easily be taken into account.
