ADAMS was used for dynamics simulation of aligning equipment in ceramic packaging line. Working principle of the mechanism was introduced. The simulation method was introduced beginning from designed structure by SolidWorks, which included model simplifying, model classification, imported into ADAMS, remodeled, applying constraint, and simulation. The actual force on cylinder was calculated and the diameter of cylinder was determined. The method of mechanics calculation on mechanism after structural design was established. The purpose was to provide reference for design of similar mechanism.
