Clamping Modeling in Automotive Flexible Workpieces Machining

Autor: Mikhail Guskov, Jérôme Duchemin, Philippe Lorong, Said Moussavi

Publikováno v: Procedia CIRP. 101:134-137

Predictive dynamic simulations of virtual machining rely on accurate representation of eigenmodes and damping factors. Historically, the modeling of flexible workpieces requires experimental updating of general modal properties, especially due to a s

International Journal of Advanced Manufacturing Technology, Springer Verlag, 2021, 115, pp.1919-1929. ⟨10.1007/s00170-021-07243-8⟩

International audience; In-process workpiece elastic deflection is the major source of geometrical error when machining low-stiffness workpieces. It creates an undercut error which needs to be corrected by time-consuming and labour-intensive operatio

How to model orthotropic materials by the discrete element method (DEM): random sphere packing or regular cubic arrangement?

Autor: Guillaume Pot, Philippe Lorong, Stéphane Girardon, Rémi Curti

Publikováno v: Computational Particle Mechanics
Computational Particle Mechanics, Springer Verlag, 2018, pp.24. ⟨10.1007/s40571-018-0202-y⟩

The discrete element method (DEM) is used for continuous material modeling. The method is based on discretizing mass material into small elements, usually spheres, which are linked to their neighbors through bonds. If DEM has shown today its ability

Modelling of part distortions due to thermo-mechanical effects with MQL machining applied to head-cylinder in a production line context

Autor: Patrice Carras, Philippe Lorong, Lounès Illoul, Théo Dorlin

Publikováno v: Procedia CIRP. 77:433-436

Wet machining is widely used in order to provide better machining conditions. However, recent studies show that it has an influence on workers’ health, manufacturing costs and environment. Therefore, solutions like dry or MQL machining are encourag

On the Factors Affecting the Accuracy and Robustness of Smoothed-Radial Point Interpolation Method

Autor: Philippe Lorong, Eric Monteiro, Idir Belaidi, Abderrachid Hamrani

Publikováno v: Advances in Applied Mathematics and Mechanics
Advances in Applied Mathematics and Mechanics, Global Science Press, 2017, 9 (1), pp.43-72. ⟨10.4208/aamm.2015.m1115⟩

In order to overcome the possible singularity associated with the Point Interpolation Method (PIM), the Radial Point Interpolation Method (RPIM) was proposed by G. R. Liu. Radial basis functions (RBF) was used in RPIM as basis functions for interpola
