Calculation Model of Lifting Resistance of Car Door Glass Based on System Deviation

He Jian

Abstract：Taking a certain vehicle model as an example， the calculation model of glass lifting resistance under the condition of system deviation is discussed. The geometric model of the glass is first established， and the glass torque is calculated by analyzing the deflection of the glass. When the torque is balanced， the glass is in the dynamic balance at the deviated position， then the lifting resistance is calculated， and finally the matching analysis with the lifter is performed.

Key words：glass deviation， balance coefficient， lift resistance， lifter matching
