SpletMaximum contact stiffness is too big. I am doing a 2D thermal expansion simulation and received the following warning: The maximum contact stiffness is too big. This may … Splet15. dec. 2016 · A general nonlinear contact model based on power law is proposed for a simple determination of the contact stiffness between a rigid steel sphere and a steel elastic half-space. Three relevant parameters are measured; maximum normal contact force, time of contact and impact velocity using a simple impact test rig.

Splet21. nov. 2013 · We investigate the contact stiffness of an elastic half-space and a rigid indenter with randomly rough surface having a power spectrum , where q is the wave vector. ... The maximum contact ... Splet29. jun. 2009 · The approximated stiffness coefficients close to an s.e.p. for bearings with clearance derived in this paper requires contact between the shaft and the bearing and that the friction in the contact can be neglected. It is further assumed that the shape of the contact structure (see Figure 1) is remained during contact. SpletIn Refs. [36,37,58,59,105,103], the Hertzian contact stiffness, bending stiffness, shear stiffness and axial compressive stiffness are all derived as a function of gear rotation angle. Correspondingly, the total effective mesh stiffness of a pair of gears is also a function of gear rotation angle through Eq. (2). here we go again sheet music
