摘　　要：构建B-C五轴机床所对应拓扑结构误差传递链的数学模型。该模型能够对低序体序列及支承件相对运动间存在的关联做出详述,且以此提出针对构建该类模型的可行方法。以该方法为基础,对得到的运动轴误差传递链进行了拓展运用,实现了对机床空间在接受微分变换之后在几何层面上出现误差所对应模型的构建,继而完成了能够对B-C五轴加工中心空间在几何层面所出现误差进行有效分析的模型的构建。The mathematical model of topological error transfer chain of B-C five axis machine tool is constructed.The model can describe the relationship between the sequence of low order body and the relative motion of support in detail,and put forward a feasible method for constructing this kind of model.Based on this method,the error transfer chain of motion axis is extended,and the corresponding model of geometric errors in machine space after differential transformation is constructed.Then the model that can effectively analyze geometric errors in B-C five axis machining center space is constructed.
