本文的主要目的是提出一种无序、电路和分支缺陷的 Stephenson-III 运动发生器的维度综合方法。利用四连杆机构的耦合器曲线、二元体的可及区域以及死点配置的几何特征的概念，提出了一种用于识别斯蒂芬森-III机构的不同回路和分支的程序。利用阶次缺陷、电路缺陷和分支缺陷的特点，提出了避免这些缺陷的约束方程。提出了一种用于无缺陷 Stephenson-III 运动发生器的维度合成的优化方法。举例说明了该方法的可行性。
The main purpose of this article is to present a method for the dimensional synthesis of Stephenson-III motion generators without order, circuit, and branch defects. Using the concepts of the coupler curve of a four-bar linkage, the accessible region of a dyad, and the geometric feature of dead-centre configurations, a procedure is proposed for identifying the different circuits and branches of a Stephenson-III mechanism. Using the characteristics of order, circuit, and branch defects, the constraint equations to avoid them are presented. An optimization approach is proposed for the dimensional synthesis of defect-free Stephenson-III motion generators. An example is given to demonstrate the feasibility of the proposed method.
