摘　　要：在给定行程速比系数和行程的设计条件下,根据偏置曲柄滑块机构图解原理图,通过分析得到曲柄长度的取值区间,推导出曲柄滑块机构的结构尺寸设计计算公式,并建立曲柄长度是最小传动角的函数方程。应用MATLAB软件平台编写程序获取α-γmin变化线图并求解最小传动角γmin具有最大值γmin(max)时曲柄长度值,将曲柄长度值代入设计计算公式,即可获得曲柄滑块机构唯一最优传动性能解,并通过实例验证此种设计方法的可行性与正确性,设计过程简捷明了。Under the design conditions of given time ratio and stroke, according to the bias sche- matic diagram slider--crank mechanism, the value interval of crank length is obtained by analysis,the structure size design formula of slider--crank mechanism is deduced and the function equation of crank length is the minimum transmission angle is built. Application of MATLAB software platform pro- gramming, the -- change line graph is acquired and when the minimum transmission angle has a maxi- mum value ,the crank length value is solved,the crank length values is substituted into the design of the formula, you can get slider--crank mechanism unique optimal transmission performance solution, the feasibility and correctness of this design is verified by an example, the design process is simple and straightforward.
