Marking process analyze in plate marking machine

Based on coupling and low damp ratio of the marking process, this paper presents a new approach for modeling system by dividing the whole process into several periodic dynamic processes, in which the new methods decouple the pressure system and position servo system and raise the damp ratio of pressure system and lower the inner-influence of paint guns. A theoretic analyses and digital simulation about the system of marking process are made at different paint pressure and different servo speed using Matlab. The simulate results give a better group of system parameters for marking machine in BaoSteel, which has good actual performance and the methods for improving the marking characteristic are given.
