The EPK series electric CNC screw press is an advanced mechanical equipment,but its dynamic characteristics and accuracy are significantly affected by the clearance of the kinematic pair.A kinematic pair is a mechanism in a mechanical system that allows two or more components to move relative to each other.The gap will cause mechanical vibration and reduced accuracy.Based on advanced finite element analysis and multi-body system dynamics software,this paper studies the impact of the kinematic pair clearance on mechanical dynamic performance in the EPK series electric CNC screw press.Research results show that the size of the kinematic gap directly affects the mechanical motion accuracy and the natural frequency of the system,which in turn affects the dynamic response and processing accuracy of the entire machine.
