Statics analysis for automotive rope-wheel glass regulator

Analyzing strength, stiffness, fatigue and wear of automotive rope-wheel glass regulator (glass regulator for short) and optimizing structure of glass regulator benefit improving working stability. Before analyzing strength, stiffness, fatigue and wear, statics analysis is necessary to be taken for investigating stress and displacement of key parts. Statics theoretical and finite element analysis of glass regulator in three kinds of working conditions (locked-rotor on the top dead center, locked-rotor on the bottom dead center, normal working) are taken. Results suggest that concentrated stress and large displacement mainly exist on guide rail. The concentrated stress also exists on slider, guide pulley and motor plate, but maximum stress value and large displacement risk on them are small. Statics analysis provides analysis of strength, stiffness, fatigue and wear with support on data and offers driving data for optimizing structure of glass regulator.
