The tangent friction matrix of equation (14) for sticking states in real and complex modes computation is plotted in figure 2c.. It couples directions 1 and 2 independently and

ABSTRACT: Among the experiment results of the DynoTRAIN project, the measurement of Y and Q forces in different curves have been corrected and used to extract a representative

Finally, a third reason for using the time integration method is that it could be used without adaptation for systems exhibiting several unstable modes in the complex

We have found numerically six solution branches ema- nating from ¯yyy := 0 0 0 in this problem: three with γ negative, which correspond to forcing the body to the right and no

C’est ainsi que nous nous sommes approchés du FabLab pour questionner sa philosophie, la remise en question économique, voire sociale qu’elle pose

Wheel-rail contact interactions and Dang Van rail fatigue index sensitivity analysis with respect to irregularities of the track geometry..

In addition to the parameters included in CONTACT, the contact model used in this article considers the combined roughness of wheel and rail on several parallel lines in the
