摘　　要：为完善现有机械结构静态对称概念体系,细致、完整地表征出各种结构静态对称及对称要素的存在形式,收集并分析了大量结构静态对称实例,重点研究了各种对称要素在实例中的存在形式及作用,建立了以对称要素为分类标准的机械结构静态对称概念体系及其对应的数学模型。最后,阐述了结构静态对称在连续实现产品功能、传递转换运动、提高功能作用强度、扩大功能作用范围的作用,为进一步研究结构静态对称的应用规律奠定了理论基础。In order to perfect the existing mechanical structure static symmetry concept system and indicate specific existing forms of structure static symmetries and symmetry elements meticulously and completely, a large quantity of instances concerning structure static symmetry were collected and analyzed deeply, especially focused on the existing forms and functions of symmetry elements among symmetry instances, and a new concept system and corresponding mathematical models of mechanical structure static symmetry were established. Finally, some functions of structure static symmetry were illustrated, such as implementing the products functions continuously, transferring and transforming motions, improving the intensity of functions, expanding the scope of functions. The research on functions of structure static symmetry can provide a theoretical basis for the further research on the application rules of mechanical structure static symmetry.
