摘　　要：利用拐点圆概念和对称连杆曲线的特性 ,导出一个简单的方程式。根据这个方程式只需选定曲柄和机架的长度 ,即可得到一系列能够产生带有较长直线段对称连杆曲线的铰链四杆机构。还可以得出直线段的长度、方位 ,并满足曲柄存在条件。把它用作前置机构 ,综合实现近似间歇运动的六杆机构 。A simple equation is presented via the theory of inflection circle and the properties of symmetric linkage curve.On condition that the length of crank and standing bar are chosen,a series of four bar linkage mechanism its linkage curve with a section of very approximate straight line will be obtained and the length of straight line path and direction and position can be gotten easily using hand calculating.The result of using these linkages as basis mechanism to synthesis a six bar interrupted mechanism is very successful.
