OBRABOTKAMETALLOV MATERIAL SCIENCE Том 23 № 3 2021 EQUIPMEN . INSTRUM TS Vol. 5 No. 3 2023 From fig. 6, it is obvious that when a load of 320 tons is applied, the crankshaft experiences the greatest tension, while the maximum shear stress is 93.008 MPa, and the minimum shear stress is 0.106 MPa. The crankshaft bearing area experiences maximum stress when a load of 320 tons is applied (fig. 7). The maximum principal stress here is 132.01 MPa and the minimum principal stress is -58.67 MPa, causing negative stresses on the end face (table 1). Fig. 4. Total deformation of existing crankshaft Fig. 5. Equivalent stress of existing crankshaft Fig. 6. Maximum shear stress in existing crank shaft
