  catalogue des cas-testsBeckers, Pierre  ; Debongnie, Jean-François ; et alReport (1996) This report describes the benchmarks which have been done with the machining simulation prototype. Detailed reference viewed: 21 (3 ULg)Comparaisons calculs-essais pour le palier de suspension J64Beckers, Pierre ; Debongnie, Jean-François ; Masset, Luc Report (1996) This report is devoted to the J64 suspension bearing benchmark. Unfortunately, the actual machining led to considerable vibrations, rendering any comparison impossible. Detailed reference viewed: 18 (3 ULg)Comparaisons calculs-essais pour le carter d'alimentation d'huile TA96Beckers, Pierre ; Debongnie, Jean-François ; Masset, Luc Report (1996) On this application, the computed results were in the opposite direction as compared to the physical tests. A sound analysis led to the result that a parasitic deformation was due to clamping deformations ... [more ▼] On this application, the computed results were in the opposite direction as compared to the physical tests. A sound analysis led to the result that a parasitic deformation was due to clamping deformations. In fact, the three supports of the work were found to be unsufficiently coplanar.

[more ▼] In this first application of the machining simulation tool prototype, great difficulties were encountered in the interpretaion of the physical test. In fact, parasitic deformations occured, with a three-lobed form. This implied the necessity of filtering the experimental data and a physical interpretation of the undue deformation. A theoretical study is performed, leading to the result that this phenomenon is due to the combined effect of the clearance of the clamping jaws and the pre-stress of the dead center.

[more ▼] In the frame of the feasability study of a machining simulation tool, this report starts from the fact that the concentrated loads which were formerly used are somewhat defective from several points of view. A procedure to compute distributed loads is described. [less ▲] Detailed reference viewed: 56 (7 ULg)Procedures de limitation des cas de chargeBeckers, Pierre ; Debongnie, Jean-François ; et alReport (1995) In the frame of the feasability study of a machining simulation tool, this report is devoted to special procedures allowing a reduction of the computed load cases in order to reduce the computational time. Detailed reference viewed: 34 (5 ULg)Description d'une méthode de reconstitution de la surface usinéeBeckers, Pierre ; Debongnie, Jean-François ; et alReport (1995) In the frame of the feasability study of a machining simulation tool, this report is devoted to the obtention of the machined surface from a series of finite element computations Detailed reference viewed: 45 (4 ULg)Recommandations relatives aux maillagesBeckers, Pierre ; Debongnie, Jean-François ; et alReport (1995) In the frame of the feasability study of a machining simulation tool, this report is devoted to the obtention of a suitable finite element mesh of the work. Detailed reference viewed: 26 (4 ULg)Procédures d'identification des paramètres de chargeBeckers, Pierre ; Debongnie, Jean-François ; et alReport (1995) In the frame of the feasability study of a machining simulation, this report describes how to compute the nodal components of the cutting forces on the finite element mesh. Detailed reference viewed: 25 (4 ULg)Catalogue des cas-tests avec justification des motifsBeckers, Pierre ; Debongnie, Jean-François ; et alReport (1995) In this first report of a research for RENAULT, a preliminary list of benchmarks is defined.
