项目摘要

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.

本研究的目的是建立一个从设计信息和装配信息中分析/可视化人工对象行为的框架，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性能的影响。CAD技术的繁荣促进了人工物体的设计，但装配、机械推理等方面的研究却没有取得进展。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无法迅速了解。由于通用机械检查程序的定制是困难的，并且由于待检查的机械的描述是复杂的，这导致机械本身的描述中的许多错误以及由部件修改引起的机械改变。这些事实使得进行正确的机械检查变得困难。如果 ...更多信息当零件设计中出现错误时，零件形状和机械描述的修改都变得必要，在设计的初始阶段几乎不可能使用机械检查。一个简单的方法来识别设施后，应建立一个虚拟空间的组成部分。因此，通过使用数据手套自由地装配机械部件，形成了使装配产品以与真实的环境相同的方式工作的支持系统。但是图形学并没有提供足够的便利来帮助新手在虚拟环境中组装机械零件。使用辅助线或力反馈装置的轴线对准被发现是有用的，以使组装操作容易。即使以这种方式决定装配程序，装配的完全自动化也是困难的，并且人工引入装配过程变得必要。在产品损坏或故障的情况下，维修是必要的。如果一个专家从事这样的工作，将导致产品价格的显着上涨。因此，在这些作品中引入非专家就变得不可或缺。为此目的，需要一个系统来指导组件I修理方法，但如果利用上述系统，则实施该系统并不困难。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新手（包括儿童）理解如何组装机械部件和组装对象的状态。少
