The forming process of rolling workpieces with different end shapes with cross wedge rolling was simulated by the software Deform-3D. And combined with the principle of blank compensation method, the influence of process parameters on the volume of the stub bar of workpiece with flat end and circular-arc end was analyzed, and the method to effectively control the concavity of rolled piece end surface is brought forward by using circular-arc billet. According to the obtained research results, the volume of stub bar is in direct proportion to the spreading angle, and decreases at first and then increases with the increasing of the forming angle, and increases at first and then decreases with increasing of the area reduction, and increases at first and then keep approximately invariant with increasing of mill length. Finally, the feasibility of using circular-arc billet to reduce the concavity were verified by rolling experiment.

“…Pretreatment. As the preparatory work of machining simulation analysis, the pretreatment setting has mainly three-steps including the completion of pre-treatment settings, generation of databases and simulation [10]. In the simulation control, the setting is changed to 80 steps for the simulation step, 1e-7s for the time increment, and every two steps for store increment.…”

Grinding is one of the most important operations in material processing. The study on grinding mechanism is difficult to carry out because of the difficulty in measuring the actual grinding temperature, stress and strain by experiments. Finite element analysis software Deform-3D is employed to create the Johnson-Cook material constitutive model for high-speed grinding simulation. Grinding model was constructed to reflect the temperature, strain and strain rate in the process of grinding 40Cr steel. The temperature of grinding area in simulation is analyzed to verify whether the finite element model is reasonable.

To promote the structure analysis efficiency of multi-section & variable taper wind turbine tower, a novel method is proposed. The effective factors are analyzed for the performances of wind turbine tower, and the main parameters of it are found out. Resolution on rapid structure analysis is presented according to standardized FEA flows. The parameterized modeling method of towers vertical section profiles and optimal FEM meshing method are described. Finally, a rapid structure analysis software is completed to check the method, and the SUT 77-1500 wind turbine is taken as the example to verify the feasibility of the method
