摘　　要：提出了研究闭链二自由度平面铰链五杆机构双曲柄存在充分条件与必要条件的新方法———"杆组法"。与现有方法相比,新方法思路简单明快、通用性好,推理过程简单清晰,结论形式简洁、概括性强;具有一定的方法论意义和推广价值。A new method--bar group method--is put forward about a study on the existence of sufficient conditions and necessary conditions for double cranks in hinged planar five-barlinkage with closed chain and two degrees of freedom. Compared with methods now available, this new method has the advantages of straightforward train of thought, good generality character, simple and clear inference process, succinct conclusion form and strong summarization, and possesses a certain sense of methodology and value of popularization.
