The Optimized Design of Crank Rocker Mechanism without the Quick-returning Characteristic

Based on the function equation,MATLAB is applied to obtain the change chart. According to the line graph by taking appropriate changes value,and the selected value and the given initial swing angle and the length of a rod,and again according to design and calculation one can easily calculate the formula based on the design length of the rest of the bar,then results can be designed to ensure that agencies have the optimum transmission performance and reasonable structure size. By this method,it does not only design the crank rocker mechanism without quick return characteristics with optimum transmission performance and reasonable structure and size,but also makes the design process simple,flexible and highly precision.
