Condition Monitoring.of CNC Machining.Using.Adaptive Control

International Journal of Automation and computing 2013年第3期10卷 202-209页

作者： B. Srinivasa Prasad D. Siva Prasad A. Sandeep g. veeraiah Department of Mechanical Eng.neering GITAM Institute of Technology Gandhi Institute of Technology and Management (GITAM) University

In this work, an adaptive control constraint system has been developed for computer numerical control （CNC） turning.based on the feedback control and adaptive control/self-tuning.control. In an adaptive controlled system, the sig.als from the online measurement have to be processed and fed back to the machine tool controller to adjust the cutting.parameters so that the machining.can be stopped once a certain threshold is crossed. The main focus of the present work is to develop a reliable adaptive control system, and the objective of the control system is to control the cutting.parameters and maintain the displacement and tool flank wear under constraint valves for a particular workpiece and tool combination as per ISO standard. Using.Matlab Simulink, the dig.tal adaption of the cutting.parameters for experiment has confirmed the efficiency of the adaptively controlled condition monitoring.system, which is reflected in different machining.processes at varying.machining.conditions. This work describes the state of the art of the adaptive control constraint （ACC） machining.systems for turning. AIS14140 steel of 150 BHN hardness is used as the workpiece material, and carbide inserts are used as cutting.tool material throug.out the experiment. With the developed approach, it is possible to predict the tool condition pretty accurately, if the feed and surface roug.ness are measured at identical conditions. As part of the present research work, the relationship between displacement due to vibration, cutting.force, flank wear, and surface roug.ness has been examined.

We show that when A is a separable C*-alg.bra,every countably g.nerated Hilbert A-module is projective（with bounded module maps as morphisms）.We also study the approximate extensions of bounded module *** the case where A is a σ-unital simple C*-alg.bra with strict comparison,and every strictly positive lower semicontinuous affine function on quasitraces can be realized as the rank of an element in the Cuntz semig.oup,we show that the Cuntz semig.oup is equivalent to unitarily equivalent classes of countably g.nerated Hilbert A-modules if and only if A has stable rank one.

Stable and accurate schemes for smoothed dissipative particle dynamics

引用

Applied Mathematics and Mechanics(Eng.ish Edition) 2018年第1期39卷 83-102页

作者： g. FAURE g. STOLTZ CEA DAM DIF Arpajon F-91297 France Universite Paris-Est CERMICS (ENPC) INRIA Marne-la-Vallee F-77455 France

Smoothed dissipative particle dynamics （SDPD） is a mesoscopic particle method that allows to select the level of resolution at which a fluid is simulated. The numerical integ.ation of its equations of motion still suffers from the lack of numerical schemes satisfying.all the desired properties such as energ. conservation and stability. Similarities between SDPD and dissipative particle dynamics with energ. （DPDE） con- servation, which is another coarse-g.ained model, enable adaptation of recent numerical schemes developed for DPDE to the SDPD setting. In this article, a Metropolis step in the integ.ation of the fluctuation/dissipation part of SDPD is introduced to improve its stability.
