Hybrid modeling method has been used to identify the weak property modules of framed hydraulic press machine in this paper, and the structures of weak property modules have been optimized, improving the design precision and rigidity of hydraulic press machine body. And it is verified that hybrid modeling, being simple, efficient and precise, is an effective method for property module identification, and is especially suitable for the complex mechanical products whose sub function carriers are difficult to constitute independent structural solids. This provides a designing method and theoretical instruction for the innovational design of complex mechanical products and has a very important instructive significance and practical value.
