Development of concrete pipe molding machine with topology optimization
In this research, a new machine for manufacturing SPC (Sulphur Polymer Concrete) pipe is designed by taking consideration of inner rotating core for mixing, compressing and giving final shape of product. Research is focused to optimize the topology of part for ensuring robust functionality. First, the concept of a new molding machine was designed by applying TRIZ principles. Among the various concepts, one of the concepts was selected using scoring techniques, where concepts are presented and compared with varieties of evaluating criteria. Topology optimization with density method has applied to design inner rotating core part for mass reduction and thereby optimum utilization of design space. Objective is focused to minimize the developed topology by maximizing stiffness. Optimized finite element topology is generated as CAD model and response charts of different design variables are generated. CATIA, OptiStruct and ANSYS are tools used for concept design, optimization of topology. To the end optimal topology is compared with the initial designed part in terms of weight and displacement and is concluded that topology optimized model maximizes overall stiffness resulting in better product design.
