摘　　要：以曲柄长度为设计参数,分别给出了按行程速比系数和最小传动角综合曲柄滑块机构的解析法,确定了设计参数的选择范围.解决了按给定行程速比系数综合最小传动角取得最大值以及按给定最小传动角综合具有最大行程速比系数的曲柄滑块机构的两类极值问题,给出了设计公式和线图.此方法既能进行设计的可行性判断,又能一次性确定机构参数,避免了迭代和验算,使机构综合工作快速准确.The crank length is treated as design parameter. The analytical synthesis method of the slider crank mechanism with time ratio and transmission angle is respectively presented. The selecting ranges of the design parameter are determined. Tow problems which make synthesis a slider crank mechanism have maximum time ratio or have maximum minimum transmission angle are completely solved by the technique of curve fitting. The design equations and curve chart are established. This method can not only judge the feasibility, but also determine the parameters of mechanism one time. The iteration and checking are avoided, so it makes the synthesis of mechanism fast and accurate.
