Global Elasticity Local Elast. SIMPACK Wind and Drivetrain Conference Methods Bearings and Mounts Force Element 70, Elasto Hydro Dynamic (EHD) Bearings With v. 8902 Impedanzce Method • Increasing complexity requires increased computation time 1. Impedance Chart Method - Interpolation in dimensionless chart - Cylindrical bearing geometry - Constant gap in axial direction (no tilting) - No surface roughness contact 2. Online FEM Method - Solution of Reynolds Equation in every time step - Arbitrary bearing geometry (Grooves, Oil supply) - Variable gap in axial direction (Tilting) - With surface roughness contact 3. EHD Method - Features as Online FEM Method - In addition local bearing deformation - With surface roughness contact SIMPACK AG, S.
