Hello! I want to ask you for help. I am a post-graduate student of the machine-building academy from Ukraine. I use Matlab to build a model for the transportation mechanism of slabs. I built the model but there were difficulties. I use a planar connection for 4 wheels. All is well. But I need to analyze the forces at the points of contact of the wheels with the rails. If the planar connection is replaced by a welded joint, then the reactions of the supports are calculated correctly. If I use planar connections, then the reactions of the supports are not calculated correctly. Please tell me what I'm wrong. Thank you in advance.
My MODEL
Model with planar joint – MODEL_PLANAR.zip
Model with weld joint – MODEL_WELD.zip
Frame step model – SBORKA.zip
Wheel step model – KOLESO.zip
FOR WELD JOINT
FOR PLANAR JOINT
