COMMERCIAL PROPOSAL: NONLINEAR DYNAMIC ANALYSIS OF THE FLEXX TILL ROLLER NODE
1. Performing numerical modeling of the agricultural machine node to evaluate the damping properties of the polyurethane insert (80–85 Shore A) under impulse loading.
2. Scope of work
Option No. 1 (Baseline):
Calculation of the rigid connection (without insert) to determine the reference impact loads on the FD211 bearing.
Option No. 2:
Calculation of the node with the polyurethane insert. Assessment of the reduction in peak forces and vibration amplitude.
Analysis: Comparison of the "Force vs Time," "Displacement vs Time" graphs, calculation of RMS vibrations, and search for resonance effects at a frequency of 16 Hz.
3. Technical stages:
Preparation. Processing of the CAD model (SolidWorks 2025), mesh discretization, setting up nonlinear "metal-polyurethane" contacts.
