【摘要】：数字化设计是以数字化技术为设计手段而进行的产品设计研发。数字化技术是在计算机技术快速发展的前提下而兴起的一种计算机辅助工程技术，它是一种崭新的产品设计研发方法，是一种用来代替真实的物理样机设计的、基于产品的计算机仿真模型的数字化设计方法。与传统的物理样机技术相比，它是一种先进的制造技术，改变了传统的设计理念，，对制造业产生着广泛深远的影响。牙科综合治疗机的数字化设计与研究对于设计和研发过程起到十分重要的作用。传统的设计与研发中通常是以机构理论作为设计的起点，更多的依靠实际经验与静态分析手段来研究设备中各类传动机构的运动情况，以搭建物理样机的形式验证设计的可行性，无法定量的得出设计结果，缺乏对于产品整体性、全局性把握和深入研究。利用相关的动力学分析软件，设计人员可以完成相关的数字化样机模型，并提供从产品前期方案的设计，到后期方案修改及优化等方面，得到准确的仿真分析结果；并且借助有限元分析软件，可通过静力分析得到构件在载荷等外因作用下产生的应力、应变和位移等的分布，通过非线性分析，可对齿轮传动机构的接触问题得到结果收敛批示图形曲线、von Mises等效应力图及接触应力图。此次牙科综合治疗机的数字化设计与研究，是以基本机械设计理论为前提，根据性能要求，确定各传动机构的设计参数后，借助先进的辅助设计及分析软件进行此次的研究课题。数字化设计在研发中的应用，对提升国内相关行业的设计水平、提升产品品质、缩短设计周期、降低研发成本都将起到一定的指导作用，做到将牙科综合治疗机的机构设计、外观设计、动态分析及有限元分析有机结合，是对设计研发过程的新尝试，课题研究所带来的成果也将成功的引入行业内部，以实现新技术的快速转化。
[Abstract]:Digital design is a product design research and development based on digital technology. Digital technology is a kind of computer-aided engineering technology rising under the premise of the rapid development of computer technology. It is a new method of product design and development. It is a digital design method which is used to replace the real physical prototype design and is based on the computer simulation model. It is an advanced manufacturing technology, which changes the traditional design concept and has a wide and profound impact on the manufacturing industry. The digital design and research of dental comprehensive therapy machine play a very important role in the process of design and development. The traditional design and development usually take the mechanism theory as the starting point of design. More rely on the actual experience and static analysis means to study the movement of various types of transmission mechanism in the equipment, to build the form of physical prototype to verify the feasibility of the design, can not be quantitative design results, lack of product integrity, Global understanding and in-depth research. Using the relevant dynamic analysis software, the designer can complete the relevant digital prototype model, and provide from the design of the pre-product plan, to the later project modification and optimization, etc. With the help of finite element analysis software, the distribution of stress, strain and displacement caused by external factors such as load can be obtained by static analysis. For the contact problem of gear transmission mechanism, we can get the result of convergent diagram, graph curve, von Mises and so on, and the diagram of contact stress. The digital design and research of the dental comprehensive therapy machine is based on the basic mechanical design theory, according to the performance requirements, after determining the design parameters of each transmission mechanism, The application of digital design in R & D will improve the design level, improve the product quality and shorten the design cycle of related industries in China. To reduce the cost of research and development will play a guiding role. It is a new attempt to combine the mechanism design, appearance design, dynamic analysis and finite element analysis of the comprehensive dental treatment machine. The research results will also be successfully introduced into the industry to achieve the rapid transformation of new technologies.
