| 摘 要： | 通过快速傅立叶变换获取预定轨迹及已知连杆曲线的特征参数，使得轨迹曲线之间的比较转化为特征参数的模糊相似度判别。根据特征参数可进一步获取连杆曲线的数学表达式，从而为连杆机构运动分析提供理论依据。

| Abstract: | By means of the fast Fouries transformation, the feature parameters of predetermi nate trace and known linkage curves can be obtioned. The comparison between tracecurves is transformed into determination of fuzzy similar degree of feature parameters.According to the feature parameter, the mathematical expression of linkage curve can befurther obtained, and then provides theory foundation for the motion analysis of link ages. |
