Research on Tube Sheet Welding Dynamic Simulation and its Stress Characteristics Based on ABAQUS

Abstract:

The article aimed at Heat exchanger tube sheet welding experiment and its processing technology programs in a certain enterprise and using the ABAQUS software to proceed simulation on high strength and matrix alloy surfacing transition alloy materials (soft or corrosion protection), which can acquire the temperature and stress field after welding which has been testified the rationality by test result, then determining the suitable heat source model and the welding parameters. At the same time, welding dynamic simulation research result provide adequate theoretical basis for welding test and lay the foundation of optimizing the process and method of surfacing welding. Through the methods of combining theoretical research and experimental verification,under the premise that meet tube sheet properties and strength of materials and related technical requirements,which reduce test cost and time and shorten manufacturing cycle and the methods have guiding significance for establishment of welding procedure.
