ABSTRACT摘要
In order to analyze positioning errors of assembly fixture of car SANTANA 2000, a 3D CAD model of fixture is built in this paper. Six typical deviation models are defined on the basis of six points positioning principle for fixture. The assembly gap distribution between door and side frame is analyzed and the influence of different deviation patterns on assembly gap is studied, and the effect of assembly gaps on door closing force is evaluated meanwhile. The results show that positioning errors of door assembly fixture is one of the most important factors to affect the door closing force.
为了分析桑塔纳2000装配夹具的定位误差，本文建立了一套夹具的三维模型。依据六点定位原则定义了六个典型的误差形式。我们首先分析了车门和门框的装配间隙分布情况，其次研究了不同偏差形式对装配间隙的影响，同时也评估了装配间隙对关门力的影响程度。分析结果显示，装配夹具定位误差是影响关门力因素中最重要的因素之一。
