The weight of the mainshaft, depending on the design, is generally 10 to 20 tons, and thus is significantly affected by the mass effect in cooling. In the present study, a cooling test was performed with a large specimen of 42CrMo4, which is often used as the material for the mainshaft, to empirically obtain the hardenability from the surface. Since the hardenability is dependent on the size of the main shaft, for standardization, DEFORM and JMatPro software programs were used to predict the hardness on the cooling curve at different positions and the predicted results were compared with the experimental hardenability results. When the mass effect was considered, the strength was higher at a position closer to the surface and lower at a position closer to the core. These experimental results were expressed as a function of mechanical strength depending on the depth. An ANSYS structural analysis was performed to calculate the equivalent stress. The safety factor was compared between the case where the mass effect was considered and the case where the yield strength was constant over the entire specimen for a more accurate evaluation of the structural safety.Structural Safety Analysis of Main Shaft for Wind Power Heavy Forging Wind Power Main Shaftwind turbine main shaft - Tongyu (China Manufacturer Heavy Forging Wind Power Main Shaft Business Type Manufacturer/Factory, Trading Company Main Products Heavy Forging, Open Die Forging, Steel Forged Part, Alloy and Carbon Steel Forging, Forged Shaft, Forged Cylinder Sleeve Bushing Hollow Bar, Forged Shaft Rotor Axie Spindle Axle, Forged Roll Cold Work Roll Back up Roll Work Rol, Steel Round Bar Big Forged, Forged Block Disc Ring Mould Forging
