Fatigue Life Analysis Of Automotive Glass Regulator Based On Abaqus And Fe-Safe

Taking automotive glass regulator (glass regulator for short) as investigative object, fatigue life of glass regulator in top dead center locked-rotor condition is analyzed by adopting the combined simulation of ABAQUS and FE-SAFE. Firstly, calculation criterion of fatigue life of glass regulator and the combined simulation steps of analyzing fatigue life of glass regulator are investigated. Afterwards, HYPERMESH is used to generate mesh of glass regulator and ABAQUS is used to finite element analyze glass regulator. Then, stress condition is obtained. Finally, stress condition, material fatigue property, loading spectrum are imported into FE-SAFE for analyzing fatigue life, and fatigue life nephograms are gained. Fatigue life nephograms suggest that fatigue life of plate curved part on slider, flanging on guide rail, the part near the mounting hole of guide pulley are short, on which risk of fatigue failure exists. This method provides theoretical basis for design of fatigue life of glass regulator.
