It will solve the field as much asby finite element of small interconnect subfields, each unit is assumed tobea proper ( simple ) approximate solution is derived, then solve the domain satisfying conditions ( such as structural equilibrium conditions ), resulting in the solution of problems. This solution isnot accurate solution, but the approximate solution, because the actual problem is simpler problem place. Because most practical problems difficult to obtain accurate solution, and the finite putation ofnot only high precision, but also can adapt toa variety plex shapes, thus e effective engineering analysis method. The design is based on the ANSYS software on the three roller bending machine ponents analysis. Compared with the traditional calculations pared, with the help puter finite element analysis method can be more efficient and precise results. Set the correct model, dividing the appropriate grid, and set a reasonable solution process, can accurately obtain analysis model of various parts of the stress, deformation and other results. The design and optimization of parts have great reference value.
