Abstract

order to study the temperature field, stress field, strain field, thinning rate and phase distribution in the hot forming process of torsion beam, the thermal mechanical coupling numerical simulation method based on LS-DYNA is adopted in this paper. Study found: Due to the different regions of part contact with the mould in the different order, the maximum principal strain area in the highest temperature region, the maximum principal stress area is located in the lower temperature region; In hot forming, the highest content of ferrite, pearlite and bainite are all less than 1%. After the end of hot stamping, austenite is mainly distributed in the highest temperature region, and the content is 22.32%, martensite is mainly distributed in the lowest temperature, and the content is 98.22%.
