Geometric accuracy allocation for multi-axis CNC machine tools based on sensitivity analysis and reliability theory
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science - Tập 229 Số 6 - Trang 1134-1149 - 2015
Qiang Cheng, Ziling Zhang, Guojun Zhang, Peihua Gu, Ligang Cai
Machining accuracy of a machine tool is influenced by geometric errors produced by each part and component. Different errors have varying influence on the machining accuracy of a tool. The aim of this study is to optimize errors to get a desired performance for a numerical control machine tool. Applying multi-body system theory, a volumetric error model was constructed to track and compens...... hiện toàn bộ
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
Finite element analysis of a cylindrical approach for shrink-fit precision gear forging dies
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science - Tập 217 Số 6 - Trang 677-685 - 2003
Murat Kütük, Ömer Eyerci̇oğlu, Nihat Yıldırım, A. Abdullah
The design of shrink-fit precision gear forging dies based on strength considerations using an analytical (thick-wall cylinders) approach and the finite element method are compared. While the two methods, analytical and finite element, agree well for the dies with no irregularities (gear teeth), the finite element method predicts much higher stress values than those of the analytical appr...... hiện toàn bộ
The effects of shear deformation on the free vibration of elastic beams with general boundary conditions
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science - Tập 224 Số 1 - Trang 71-84 - 2010
Jiong Li, Hongxing Hua
Free vibration characteristics of shear deformable elastic beams subjected to different sets of boundary conditions are investigated. The analysis is based on a unified one-dimensional shear deformation beam theory. The governing equations of the elastic beams are obtained by means of Hamilton's principle. Four different boundary conditions are considered. The natural frequencies and mode...... 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
Tribology of the ring—bore conjunction subject to a mixed regime of lubrication
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science - Tập 223 Số 4 - Trang 987-998 - 2009
Prakash Chandra Mishra, Homer Rahnejat, Paul D. King
This paper provides a detailed analysis of the compression ring—bore/liner conjunction. The analysis includes ring—bore conformability and global in-plane deformation of ring fitted in situ. The analysis for fitted ring in an out-of-round bore shows very good agreement with precise measurements, using a coordinate measuring machine. The analysis also includes the lubricated conjunction un...... 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
Benchmark numerical solutions for two-dimensional fluid–structure interaction involving large displacements with the deforming-spatial-domain/stabilized space–time and immersed boundary–lattice Boltzmann methods
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science - Tập 232 Số 14 - Trang 2500-2514 - 2018
Yuanqing Xu, Yanqun Jiang, Jie Wu, Yi Sui, Fang-Bao Tian
Body-fitted and Cartesian grid methods are two typical types of numerical approaches used for modelling fluid–structure interaction problems. Despite their extensive applications, there is a lack of comparing the performance of these two types of approaches. In order to do this, the present paper presents benchmark numerical solutions for two two-dimensional fluid–structure interaction pr...... hiện toàn bộ
Experimental and Numerical Investigations on the Air-Pumping Phenomenon in High-Speed Spur and Helical Gears
Proceedings of the Institution of Mechanical Engineers, Part C: Journal of Mechanical Engineering Science - Tập 219 Số 8 - Trang 785-800 - 2005
Yasser Diab, Fabrice Ville, Haruo Houjoh, Laurent Grémillard, Philippe Velex
An approximate hydrodynamic model of the air-lubricant pumping by spur and helical gears, which makes it possible to predict the compression-expansion process by the meshing teeth, is presented. The simulated pressure patterns correlate well with the experimental evidence obtained from a specific test rig for both spur and helical gears. Finally, it is shown that this pumping phenomenon c...... 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
