| Abstract: | Motion analysis of cam mechanism has an important effect and great research value on optimization design of mechanism. Several motion analysis methods of cam mechanism have been evaluated and their limitation and weakness are pointed out, then cubic spline function is applied to cam mechanism's motion analysis and its motion analysis equation is built based on curb spline function. Finally, this method is used for the switching tooth cam mechanism of printing machine and the complete motion analysis is carried out. Experimental results show that the approach is more correct and superior than earlier and traditional methods. |
