| 英文摘要 | A constitutive equation was established based on stress-strain curves of S34MnV at different strain rates and high temperatures. The coupling of thermal-mechanical process in bending large marine crankthrow was simulated by using ABAQUS code. From the simulation results, the strain-stress field and temperature field in the forging process were obtained. In order to analyze the mechanism of metal flow of crankthrow, the evolutions of the hydrostatic pressure and the surface tensile/compressive stress of typical positions on the crankthrow were investigated. The simulated defect positions, such as the "slim waist", crack and "horn mouth" etc, as well as the final shape and size of the crankthrow agree well with the experimental ones. Furthermore, an improved suggestion was given, which could be helpful to optimize the forging parameters. |
