Development of Design Methodology for Weldel Structures with Simplifyed Jigs and Robots.

这项工作的目的是通过合理化焊接结构的设计方法来简化夹具和机器人。到目前为止，焊接结构的设计没有适当考虑夹具和机器人。因此，我们必须使用非常复杂的夹具和过于复杂的双关节机器人并不罕见。这导致了整体结构质量的恶化。在这项工作中，我们基于方向码的思想开发了一种新的形状模型。我们的新模型的独特之处在于它以列表的形式表示形状。因此，可以将许多属性附加到列表中，并且非常有利的是，我们可以毫不困难地提取表单特征，因为表单特征可以表示为某个子列表。如果有更多的计算机容量，我们的形状模型可以很容易地扩展到三维。

This work was carried out with the aim of simplifying the jigs and robots by rationalyzing the design methodology for welded structures. Up until now, welded structures have been designed without proper consideration of jigs and robots. Thus it is not rare that we have to use very complex jigs and too complicated too aduanal robots. This in consequence brought forth the deteroration of struc-tural quality as a whole.In this work, we developed a new shape model based on the idea of directional codes. Our new model is unique in that it represent a shape in the form of lists. Therefore many attributes can be attached to the lists, and what is very advantageous is that we can extract a form feature without any difficulty because a form feature can be expressed as a certain sublist.Our shape model can be easily extended to three dimension if more computer capacity is available.
