摘要/Abstract

摘要： 根据解域综合理论给出了一种单自由度八杆机构的综合方法.首先，在对机构设计要求进行分析的基础上给定4R开链的4个位置.然后，为综合生成单自由度八杆机构在4R开链上添加3个RR杆，同时根据添加RR杆时所得解曲线建立解域.最后，剔除解域中不满足设计要求的机构解，形成最终的可行解域.设计者可以直观准确地在可行解域内选取可行机构，这有效地解决了四位置综合机构选取的盲目性问题.综合示例表明，解域综合理论与方法为快速设计出满足要求的八杆机构提供了一个简单有效的途径.

Abstract: An approach to synthesize a 1-DOF eight-bar linkage was given based on solution region synthesis theory. Firstly， the 4-positions of a 4R open chain were found by analyzing the design requirements. Secondly， for synthesizing the eight-bar linkage， three RR links were added to the 4R open chain. Meanwhile， the solution region could be built by the solution curves， which were gotten when RR links were added. Finally， the feasible solution region was gotten by removing the linkages， which did not meet the design requirements. The designers could directly and accurately choose the linkage from the feasible solution region， and solved the problem of blind choice. The example shows that the solution region theory and method offers a simple and effective way for the rapid design of an eight-bar linkage with meeting the requirements.

Key words: eight-bar linkage, 4-positions synthesis, 4R open chain, solution curve, solution region
