【摘要】：在世界经济快速发展和经济全球化进程中,各行各业都在向功能化、多样化、自动化、个性化发展,产品竞争愈演愈烈,企业为了满足市场需求和保持竞争力,就不得不持续地寻求创新。因此,如何创新和提高产品的竞争力,是当前全球各行各业都在探索的热点。而发明问题解决理论—TRIZ作为解决工程问题的强大系统化创新工具,被越来越多研发人员用来解决工程问题。本文结合TRIZ理论和行星齿轮系统的国内外现状,对现有的行星齿轮专利利用TRIZ理论中的竞争性专利规避技术进行求解,进而形成创新性的方案,针对特定工况,对新方案进行机械设计,并运用虚拟样机技术对之进行验证。主要内容如下:第一:通过遴选大量专利文献,总结归纳出基于TRIZ理论的专利规避流程。依据专利规避流程,通过检索词“行星齿轮”“浮动”,完成对专利的初选。再通过专利IPC分类号中的技术主题,筛选出适合的发明专利。利用TRIZ的功能分析工具,对专利进行功能分析,得到其功能模型,然后对核心组件实施裁剪,并利用TRIZ工具对裁剪模型进行求解,得到创新性的方案,完成概念设计。第二:对得到的新方案,依据实际工况,进行机械设计,得到各部位零件的具体尺寸。依据已有的尺寸,利用三维PTC Creo实体建模软件完成对零件体和装配体的建模。第三:利用PTC Creo软件中的Simulate结构分析模块对典型零件体进行机械强度分析,验证设计参数的合理性。第四:利用PTC Creo软件中的Mechanism机构仿真模块,通过建立约束和连接,施加相应的驱动,得到机械系统的虚拟样机,经过仿真就可以得到各构件的机械性能(位移、速度、加速度和力等)曲线,验证装置的可行性。我们的工作证明,应用TRIZ专利规避技术来规避竞争对手的专利是行之有效的,对我国企业的结构调整和转型升级具有很强的实用价值,指导作用。
[Abstract]:In the rapid development of the world economy and the process of economic globalization, various industries are becoming functional, diversified, automated, personalized development, product competition intensified, enterprises in order to meet market demand and maintain competitiveness, You have to keep looking for innovation. Therefore, how to innovate and improve the competitiveness of products is a hot spot in various industries all over the world. As a powerful systematic and innovative tool to solve engineering problems, the theory of inventing problem solving-Triz is used by more and more R & D personnel to solve engineering problems. Combined with TRIZ theory and the current situation of planetary gear system at home and abroad, this paper solves the existing planetary gear patent by using the competitive patent circumvention technology in TRIZ theory, and then forms an innovative scheme, aiming at specific working conditions. The mechanical design of the new scheme is carried out, and the virtual prototype technology is used to verify it. The main contents are as follows: first, through the selection of a large number of patent literature, summed up and concluded based on TRIZ theory of patent evasion process. According to the patent circumvention process, the patent selection is completed by using the key word "planetary gear" and "floating". Then through the technical theme of patent IPC classification number, the suitable invention patent is selected. By using the function analysis tool of TRIZ, the functional model of patent is obtained, and then the core components are clipped, and the clipping model is solved by TRIZ tool. The innovative scheme is obtained and the conceptual design is completed. Second, according to the actual working conditions, mechanical design is carried out to obtain the specific dimensions of the parts. According to the existing dimensions, 3D PTC Creo solid modeling software is used to complete the modeling of parts and assembly parts. Third, the mechanical strength of typical parts is analyzed by using Simulate structure analysis module in PTC Creo software, and the rationality of design parameters is verified. Fourth: using the Mechanism mechanism simulation module in the PTC Creo software, by establishing the constraint and connection, applying the corresponding drive, the virtual prototype of the mechanical system can be obtained, and the mechanical properties (displacement, speed, speed) of each component can be obtained by simulation. Acceleration and force curves to verify the feasibility of the device. Our work has proved that it is effective to use TRIZ patent evading technology to circumvent the patent of competitors. It is of great practical value and guidance to the structural adjustment and transformation and upgrading of Chinese enterprises.
