The effects of ironing speed on the mechanical properties of tin bronze tubular parts were investigated by Simufact finite element simulation software with equivalent plastic strain and the equivalent stress of the workpiece after simulation as evaluation criteria.The tensile strength

elongation and deformation force of the forming parts were taken as the performance indexes to verify the simulated results.The results show that with the increase of ironing speed

the equivalent plastic strain and equivalent stress of tin bronze cylindrical parts are decreased firstly and then decreased.With the ironing speed of 15 mm/s

deformation force

the equivalent plastic strain and equivalent stress as well as tensile strength of forming a minimum parts reach the minimum values

while elongation is the highest value.
