Prediction and Optimization of Wear Depth on Rectangular Tube Surface in Roll Forming

The outer surface of the tube is worn under interaction between velocity difference and rolling pressure, in process circular into a rectangular tube. In order to predict wear depth, according characteristics roll forming, causes forming are analyzed. finite element model was established based on Archard theory, 40 mm × 27.5 3 SUS304 stainless steel simulated. simulated results were compared with test tubes same size material, areas found be highly consistent, which verified accuracy model. effects friction coefficient flat roller angular simulation depth analyzed, regression by response method. showed that had greatest effect depth; moreover, second, vertical lowest. minimum value optimized, optimization scheme optimized value, error two values less than 5%, correctness after reduced 64.69% before optimization, effectiveness results.
