基于模糊匹配的平面连杆机构反求设计研究

Study on reverse design of planar linkage based on fuzzy match

对平面连杆机构曲线进行了分析,提出了用一组特征参数来描述连杆曲线,建立了连杆曲线图谱库,并将模糊论应用于连杆机构的曲线匹配,从而获取所求的机构参数。最后给出了应用实例,证实了该方法的可行性与有效性。

This paper analyzes the curve of planar linkage, puts forward the idea that using a group of feature parameter to describe linkage curve, establishes the database of linkage curve, applies the fuzzy theory to curve matching of linkage mechanism, and accordingly obtains the parameter of the desired mechanism. Finally an application instance is also given to make sure the feasibility and validity.
