摘　　要：对含间隙的平面连杆机构进行了动力学建模，并采用Ｐｏｉｎｃａｒｅ映射的方法研究了含间隙机构动力学行为的混沌现象，发现了含间隙机构的动力学响应存在奇异吸引子，而且间隙是导致混沌和影响Ｐｏｉｎｃａｒｅ映射形态的主要因素。In this paper, dynamic equations of the linkage with a clearance are set up using impact pair model, and Poincare map is applied to study the chaotic behavior of the response in the linkage with a clearance. According to Poincare map, it is found that clearance is the important fact that causes chaos and affects figure of Poincare map.
