【摘要】：为综合得到具有两移两转运动特征的混联机构,基于分形理论和机构拓扑图,提出一种系统的混联机构型综合与分析方法。介绍了机构拓扑图和分形理论的概念及关系;叙述了机构的运动特征和运算法则,运动特征包括路径、支链和运动副的定义与表达形式,运算法则含有路径法则串并联计算规则;建立了混联机构与分形的关系模型,归纳出混联机构构型综合的具体步骤,并综合出具有两转两移运动特征的混联机构。提出混联机构运动特征的分析方法,并用该方法分析了所综合出的两转两移混联机构的末端运动特征,验证了该构型的正确性,证实了所述方法的可行性。
[Abstract]:In order to synthetically obtain a hybrid mechanism with the characteristics of two moving and two rotating motion, a systematic method of hybrid on-line configuration synthesis and analysis is proposed based on fractal theory and mechanism topology graph. The concepts and relationships of mechanism topology and fractal theory are introduced. This paper describes the kinematic characteristics and algorithms of the mechanism, including the definition and expression of the path, the branch chain and the kinematic pair, and the algorithm contains the rules of the series-parallel calculation of the path-rule, and establishes the relationship model between the hybrid mechanism and the fractal. The concrete steps of configuration synthesis of the hybrid mechanism are summarized, and the hybrid mechanism with the characteristics of two rotation and two moving motion is synthesized. The analysis method of the motion characteristics of the hybrid mechanism is put forward. The method is used to analyze the end motion characteristics of the two-rotation and two-shift hybrid mechanism. The correctness of the configuration is verified and the feasibility of the proposed method is verified.
