Numerical investigation of weather strip extrusion forming process by thermal flow analysis

Thermal flow simulation can be used to study the fluid flow and heat transfer for a wide variety of engineering equipment. Flow simulations with the advent of computer architectures with superfast processing capabilities are rapidly emerging as an attractive alternative to conventional thermal flow analysis which is either too restrictive or expensive. In thermodynamic applications, increase of thermal efficiency of heat exchangers (i.e. radiators, cooling towers, condensers, intercoolers) is essential for compact design and improving whole cycle efficiency thus improving economic viability of the system. This paper outlines the process taken to optimize the geometry of conventional heat exchanger. Models were drawn into Solidworks and a computational domain was created. Solidworks Thermal Simulation was used to iterate toward a converged solution with the goal of obtaining a better efficiency of the heat exchanger. The results are analyzed and compared between two differently designed heat exchangers to find out the improvements. These practices were detailed in hopes that further research would use the ground work laid out in this paper to redesign existing heat exchangers.

Production Dynamic

The cardan belong to dial the fork kind parts, its forming is difficult and forming high quality requirements. Establish macro-micro coupling, and a simulation model for the cardan negative extrusion forming process, a numerical simulation considering the deformation and heat conduction, deformation heat production, friction heat production, dynamic recrystallization and so on many factors. Analyze the deformation process detection cardan anti extruded deformation in advance and is extruded deformation. Meanwhile analysis showed that the cardan forgings have internal 59.929% area completely modification, have 4.7944% area did not happen dynamic recrystallization and didn't get forging modification, and forecasts the cardan internal grain size and distribution, the micro analysis for the prediction of forgings performance and design heat treatment process, provides the basis.
