摘　　要：通过分析推导出基于最佳传动角双曲柄机构的设计公式,当给出双曲柄机构k、[γ]和某一杆几何尺寸时,利用所推导的设计公式就可方便地求出其余各杆几何尺寸。设计公式中γmin取值介于[γ]≤γmin<φ/2,避免了因γmin盲目取值而造成的设计反复。依据双曲柄机构的闭环矢量模型图构建其运动仿真数学模型并应用MATLAB编写程序,运行程序就可输出基于最佳传动角的双曲柄机构从动曲柄和连杆的转角、角速度和角加速度随主动曲柄转动而变化的运动仿真曲线图。By analysis a design formula of double crank mechanism was deduced based on optimum transmission angle. When given double crank mechanism k,[γ]and a rod geometry size,using the design equations we easily find geometry size of the rest rods. Design γminformula value between [γ]≤γminφ 2,avoiding γminrepeated design caused by the blind value. Closed-loop vector model based on double crank mechanism diagram constructed mathematical models and their motion simulation using MATLAB programming,you can run the program output based on double crank mechanism driven crank and connecting rod optimum transmission angle of rotation, angular velocity and angular acceleration with active cranking motion simulation curve.
