基于系统偏差的车门玻璃升降阻力计算模型

何剑

摘 要：以某车型为例，讨论系统偏差情况下的玻璃升降阻力计算模型。先建立玻璃的几何模型，通过分析玻璃的偏转量计算玻璃力矩，当力矩平衡时，玻璃处于偏差位置下的动态平衡，再进行升降阻力计算，最终与升降器进行匹配分析。

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
