Abstract:Apply the finite element software MARC to simulate the drum instability phenomenon of loading workpiece under the condition of different clearance ratio;Analyse the influence law of clearance ratio between mandrel and workpiece on the drum instability and verify it by experiment,so as to provide theory instruction for researching the manufacturing technology of cylindrical workpiece with extra thin-wall and height diameter/thickness ratio.
Keywords:Thinning Spinning  Clearance Ratio  Drum Instability  Height Diameter/Thickness Ratio
