Simulation at low speeds

Wr_coupl_pe0 is a wheel/rail-coupling that handles vehicle speeds down to 0. [km/h]. At speeds under 0.02 [m/s] the code switches from Kalker to Coulomb friction theories.

This directory contains the following examples:

runf/break_mu.3_rkona_Vo5.tsimf
After 0.5[s] a break friction moment is applied to all wheelsets. The simulation shows the retardation down to full stop.
runf/front-back_mu.3_rkona.tsimf
The vehicle starts at zero velocity. After 1[s] a square shaped pitch moment is applied on all wheelsets. Due to the pitch moment the vehicle will start to move forward and backward.
runf/curv_mu.3_uic60i40.tsimf
The vehicle enters a curve with a speed of 1[m/s]. The vehicle brakes due to friction forces in the contact surfaces down to full stop.
