Aim the cam contour design and motion simulation based on ADAMS provide an advanced and intuitive method for cam contour design, which has great advantages over the traditional graphic method and analytical method. Through ADAMS virtual prototype design, the author generates virtual trajectory curve and stretches it into cam contour, and completes the analysis of motion parameters at the same time. According to the results of parameter analysis, the law of push motion is changed to avoid rigid impact in motion. The analysis and design method is helpful to design a reasonable cam profile more accurately.
