Volumetric Error Modelling, Measurement, and Compensation for an Integrated Measurement-Processing Machine Tool
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science - Tập 224 Số 11 - Trang 2477-2486 - 2010
K Wang, Xian Jun Sheng, Ren Ke Kang
The volumetric error of a measurement-processing integrated machine tool was studied by using a complicated surface workpiece grinding machine as a special example. The model of volumetric error was established by using homogeneous transformation matrices, and the effect of volumetric error on coordinate transformation between the measurement and the processing work station was analysed. ...... hiện toàn bộ
A theoretical model for the contact of elastoplastic bodies
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science - Tập 216 Số 4 - Trang 421-431 - 2001
Long-yuan Li, Chuan‐Yu Wu, Colin Thornton
The paper presents a theoretical model for the normal contact of a rigid sphere with an elastic-perfectly plastic half-space or an elastic-perfectly plastic sphere with a rigid wall. Formulae describing the force-displacement relationship for static contact problems and the coefficient of restitution for dynamic impact problems are derived. The present model can be considered as a modific...... hiện toàn bộ
The role of vibration and pass number on microstructure and mechanical properties of AZ91/SiC composite layer during friction stir processing
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science - Tập 236 Số 5 - Trang 2312-2326 - 2022
Behrouz Bagheri, Amin Abdollahzadeh, Farzaneh Sharifi, Mahmoud Abbasi
In this study, nano-sized SiC particles are added to AZ91 magnesium alloy using friction stir processing (FSP) and friction stir vibration processing (FSVP) to produce surface nano-composite layers. FSVP is a modified method of FSP in which the specimen is vibrated during FSP. The influence of FSP and FSVP pass numbers on mechanical and microstructural behaviors of the developed surfaces ...... hiện toàn bộ
A review on assembly sequence generation and its automation
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science - Tập 230 Số 5 - Trang 824-838 - 2016
M. V. A. Raju Bahubalendruni, Bibhuti Bhusan Biswal
Sequence of feasible mechanical assembly operations plays significant role in overall cost optimisation process for manufacturing industry and thus great importance is given to assembly sequence generation from past four decades. Though achieving at least one feasible sequence is focused in the earlier stages of research, the introduction of soft computing techniques attracted the industr...... hiện toàn bộ
Vibration and buckling analysis of functionally graded sandwich plates with improved transverse shear stiffness based on the first-order shear deformation theory
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science - Tập 228 Số 12 - Trang 2110-2131 - 2014
Trung-Kien Nguyen, Thuc P. Vo, Huu‐Tai Thai
An improved transverse shear stiffness for vibration and buckling analysis of functionally graded sandwich plates based on the first-order shear deformation theory is proposed in this paper. The transverse shear stress obtained from the in-plane stress and equilibrium equation allows to analytically derive an improved transverse shear stiffness and associated shear correction factor of th...... hiện toàn bộ
A nonlocal sinusoidal plate model for micro/nanoscale plates
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science - Tập 228 Số 14 - Trang 2652-2660 - 2014
Huu‐Tai Thai, Thuc P. Vo, Trung-Kien Nguyen, Jaehong Lee
A nonlocal sinusoidal plate model for micro/nanoscale plates is developed based on Eringen’s nonlocal elasticity theory and sinusoidal shear deformation plate theory. The small-scale effect is considered in the former theory while the transverse shear deformation effect is included in the latter theory. The proposed model accounts for sinusoidal variations of transverse shear strains thro...... hiện toàn bộ
A study of laser welding modes with varying beam energy levels
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science - Tập 223 Số 5 - Trang 1141-1156 - 2009
G. Buvanashekaran, N. Siva Shanmugam, K. Sankaranarayanasamy, R Sabarikanth
The energy of a laser beam is generally calculated based on the laser power and its processing speed. In this work, the laser welding modes such as conduction, conduction—penetration, and keyhole welding of thickness 1.6, 2, and 2.5 mm AISI304 stainless steel sheets, respectively, are studied at different beam energy levels. A series of bead-on-plate trials are conducted using a 500 W con...... hiện toàn bộ
A comparative study of treatment of two-dimensional two-phase flows of steam by a Runge-Kutta and by Denton's methods
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science - Tập 221 Số 6 - Trang 689-706 - 2007
F. Bakhtar, M Y Zamri, J. M. Rodríguez-Lelis
This paper describes a comparative study of the treatment of two-dimensional nucleating flows of steam using two different time-marching numerical schemes. A treatment based on Denton's scheme but a refined grid has been available from earlier work. To compare with this a treatment based on the Runge-Kutta scheme has been developed, which is described. Solutions using this scheme and a si...... hiện toàn bộ
Effect of cooling liquids on cutting process using diamond segmented disc of natural stones
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science - Tập 227 Số 10 - Trang 2315-2327 - 2013
İrfan Ucun, Kubilay Aslantaş, I.S. Buyuksagis, Süleyman Taşgeti̇ren
In this study, various cooling liquids considered as alternatives to water were investigated for cutting performance of diamond sawing disc utilized in cutting process of natural stones. In experiments, four various cooling liquids such as water, Ace-Cool, boron oil and liquid soap and two different natural stones (Blue Pearl and Nero Zimbabwe) were used. Down-cutting mode was selected fo...... hiện toàn bộ
Nonlinear effects of viscoelastic fluid flows and applications in microfluidics: A review
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science - Tập 234 Số 22 - Trang 4390-4414 - 2020
Chao Yuan, Hong-Na Zhang, Yuke Li, Bin Li, Jian Wu, Feng‐Chen Li
Viscoelastic fluid naturally has both viscous and elastic properties. Therefore, there are two sources of nonlinear effects, namely inertial and elastic nonlinearities. The existence of elastic nonlinearity brings about various interesting flow phenomena in viscoelastic fluid flow, especially in microfluidics where the inertial nonlinearity can be negligible while the elastic nonlinearity...... hiện toàn bộ
