一、问题的提出 曲柄摇杆机构的最小传动角γ_(min)是对机构进行动力分析和设计时必须考虑的一个重要性能指标,它的数值可用判别最小传动角的三个命题来确定。但是,这要取决于机构的两固定铰链中心A、D与摇杆的活动铰 First, the issue of the proposed crank rocker mechanism of the minimum transmission angle γ_ (min) is the mechanism for dynamic analysis and design must be considered an important performance indicators, its value can be used to determine the minimum transmission angle of the three propositions to determine. However, it depends on the articulation between the two fixed hinge centers A, D of the mechanism and the rocker
