Dynamic Contact Problem for Slide Hinge ()
Abstract
Contact analysis can be either static or
dynamic. In static contact analysis, the position on the contact surface is
constant. In dynamic contact analysis, the position on the contact surface
changes at every time step. In static contact analysis, the computing results
(stress, strain, etc.) of contact states have been verified through the Hertz
contact problem in literature. On the other hand, there has been insufficient
research into dynamic contact analysis. The contact algorithm is insufficiently
constructed in finite element model (FEM) discretization. The gap between two
objects cannot be calculated accurately. A contact method is demanded for
artificial parameters. Inappropriate setting of artificial parameters causes
artificial numerical oscillations on the contact surface between objects. To
develop a high-reliability satellite, we started the development of FEM
contact-friction modeling techniques in this study. A dynamic contact method
was realized by using the appropriate parameters required in the contact
analysis. We verified the reproducibility of the physical behavior of the
contact friction via numerical simulation techniques by using a computational
model of the hinge joints.
