The static and dynamic characteristics of the beam of a gantry-type machining center are analyzed by means of ADAMS and ANSYS. Considering effect of gravity and cutting forces, the static deformation of the beam is obtained after calculating the interacting forces between the guide and the slide block by ADAMS. Moreover, the contact parameters of the guide surface are acquired by dynamic tests and parameter identification, then they are applied to the simulation model of the beam-slide box system, whose natural frequencies and modal shapes are achieved by modal analysis. Furthermore, the effect of changes of the contact parameters on the dynamic behavior of the beam-slide box system is also investigated.

In order to deeply reveal the smoothing mechanism of roller burnishing and to overcome the difficulty in the selection of the burnishing cross feed dependent mainly upon experiences and hand feel, the roller burnishing process is taken as an issue of plane-strain mechanics and the micro-plastic deformation area is determined on the basis of the Von-Mises yield criterion and by using the Boussinesq-Flamant solution. Then, the contact pressure distribution is obtained based on the Hertz contact theory, and the stress distributions in the burnishing tool and the workpiece are respectively revealed.

Where contact is deemed by the referee to be too strong, but does not diminish the competitor's chances of winning, a warning may be given. A second contact under the same circumstances will be penalised by KEIKOKU and IPPON, given to the opponent. A third offence will be given HANSOKU CHUI and NIHON, to the injured competitor. A further offence will result in disqualification by HANSOKU.

In this paper, a 4-node plate element combined with rivet element and contact element is employed to analyze two typical rivet joint structures, i.e., lap joint and butt joint. The penetration between two sub-plates in the lap zone or butt zone is avoided by introducing contact element in the proposed FE model. Bending deformation and its effect on in-plane displacement of the two typical rivet joint structures are studied.
