Study on the Influence of Clearance Ratio between Mandrel and Workpiece on the Spinning Stability of Cylindrical Workpiece with Extra Diameter-Thick Ratio.

In spinning process, our group found that the main problem of extra diameter-thick ratio Nickel alloy tube spinning was drum instability and the main influence factor was clearance ratio between mandrel and workpiece. 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 extra diameter-thick ratio.
