Analysis on Welding Temperature Field and Stress Field of Boring Bar of New Boring Machine

Abstract Ansys software is used to simulate the welding process of boring bar new cylinder head machine. The indirect coupling method analyze temperature field, then stress field and deformation. It found that for double support structure, highest occurs at outer stiffened plate small diameter end, lowest both ends inner structure. deformation whole structure mainly comes from axial deformation, maximum large end rib plate. Because role supporting web limit firmer has ability anti-deformation. In terms technology, influence caused by can be compensated compensation design machining amount.
