平面四杆机构急回特性分析

Analysis of the Quick Return Characteristic in Four-bar Linkage

根据教科书四杆机构急回特性的概念,分别对摆动导杆机构、曲柄滑块机构和双曲柄机构进行是否具有急回特性分析,并对双曲柄机构急回特性和曲柄滑块机构及导杆机构急回特性的程度的不同进行分析,有助于更好地理解急回特性。

According to the quick-return characteristics of four-bar linkage concept in text book, the quick return characteristics of the oscillating guide-bar mechanism, double crank mechanism, slider-crank mechanism are analyzed. The difference of the quick return characteristics of double crank mechanism, slider-crank mechanism and guide-bar mechanism are analyzed, and the results are helpful to understand quick-return characteristics better.
