Research on reasoning of machinery based on both design and assembly information and its application

本研究的目的是建立一个从设计信息和装配信息分析/可视化人造物体行为的框架，并创建一个虚拟现实系统，阐明设计变更和装配过程修改对机械设备的影响。计算机辅助设计的繁荣促进了人造物体的设计，但装配、机械推理并没有取得进展。基于零件公差的设计检查成为可能，但零件形状和装配程序对机械的影响不能很快知道。由于通用机械检查程序的定制困难，并且由于要检查的机械的描述复杂，这导致在对机械本身的描述和由于部件修改而引起的机械改变中存在许多错误。这些事实使得进行正确的机械检查变得困难。如果…零件设计中的错误较多，零件的形状和机械描述的修改都是必要的，在设计初期几乎不可能进行机械检查。在虚拟空间中组装部件后，应该建立一种简单的方法来识别设施。因此，通过使用数据手套自由地组装机械部件，形成了使装配产品以与真实环境中相同的方式工作的支撑系统。但是图形技术不能提供足够的便利来帮助新手在虚拟环境中装配机械零件。使用辅助线或力反馈装置的轴对准被发现有助于使装配操作变得容易。即使以这种方式决定组装过程，组装的完全自动化也是困难的，并且需要人工引入组装过程。在产品损坏或故障的情况下，维修变得必要。如果一位专家从事这类工作，将导致产品价格的显著上涨。因此，在这些作品中引入非专家就变得不可或缺了。为了达到这个目的，需要一个指导程序集I修复方法的系统，但如果开发上述系统，实现该系统并不困难。我们已经证实，引入口语以确保自由交流和允许错误的组装操作有助于包括儿童在内的新手了解如何组装机械部件和组装对象的状态。较少

The purpose of this research is to make the framework that analyzes / visualizes the behavior of an artificial object from the design information arid assembly information, and to create a virtual reality system clarifying the affect that the design change and modification of assembly procedure give to facility of machinery. The design of an artificial object is facilitated with the prosperity of CAD, but assembly, machinery reasoning do not make progress. Design inspection on the basis of parts tolerance becomes possible but the affect that part shapes and an assembly procedure give to the machinery cannot be known quickly. As customization of the general purpose machinery inspection program is difficult, and because a description of the machinery to be inspected is complicated, this causes many errors in the description of the machinery itself and machinery alteration caused with the parts modification. These facts makes it difficult to practice a correct machinery inspection. If the … More re are errors in the part design, both of the part shape and the modification of the machinery description become necessary, It is almost impossible to use machinery inspection at the initial stage of the design. A simple approach to identify the facility should be established after having made up parts in a virtual space. So a support system to has an assembly product work in the same way as in the real environment is made by assembling mechanical parts using a data glove freely. But graphics does not offer enough facility to help novices assemble mechanical parts in virtual environment.. An axis alignment using auxiliary lines or a force feedback device are found to be useful to make assembly operation easy. Even if an assembly procedure is decided in this way, complete automation of assembly is difficult, and human introduction to assembly process becomes necessary. And repair becomes necessary in the case that a product was damaged or broke down. If an expert were engaged in such tasks, a remarkable rise of product price would be caused. So introduction of non-experts into those works becomes indispensable. A system instructing assembly I repair method is necessary for that purpose, but it is not difficult to implement the system if the above mentioned system is exploited. We have confirmed that introduction of spoken language to secure a free communication and permission of erroneous assembly operation help novices including children understand how to assemble mechanical parts and the state of an assembled object.
