Heat and Mass Transfer Finite Element Simulation of Clay Ceramic Prototype in High-Temperature Drying
In the DPST (Direct Prototype Spray Tooling) sprayed directly prototype tooling technology of Huazhong University of Science and Technology , due to brittle characteristics of ceramic materials, there was low efficient in the processing of large mold .The study would obtain sprayed ceramic prototypes through Industrial robots directly milling of ceramic rough technology, However, clay ceramic prototype embryos after milling would occur large shrinkage in the high-temperature drying and consolidation. In the paper it has established a clay material mathematical model of heat and mass transfer in the high-temperature drying process, and carried out finite element simulation in the ABAQUS, obtained shrinkage deformation law of the clay material.
