摘　　要：讨论了能够产生对称连杆曲线的铰链四杆机构的几何特征。提出了一种简单的图解综合法,它可以综合能够产生对称连杆曲线的铰链四杆机构并使对称的连杆曲线在给定的厚度S(在对称轴方向上)和宽度(在垂直与对称轴方向上)范围内。还提出了一种能产生带有一段近似直线的对称连杆曲线的四杆机构的综合、简单、实用的新方法。In this paper the geometry properties of the plane four-bar linkage which can generate a symmetric path are discussed.A simple method of graphical synthesis is presented.It is used to synthesize a plane four-bar linkage path and can make the path in the region of given thickness (at the direction of symmetric axis)and width.The other new method of how to synthesize a four-bar linkage path with a section of approximate line is presented also.
