It is in urgent need of R&D with varying ellipse machining lathe for high-power marine diesel engine piston,which are imperative in important economic areas,such as large vessels,heavy motorcycle,automotive,aerospace and construction machin-ery,and others in China. A special fixture using for the processing of large-diameter piston lathe was designed,and its three-dimen-sional (3-D)modeling and finite element simulation analysis (FEA)were carried out. It is proved that the rational design of the fix-ture can meet the work requirements.
