ANSYS-based sequential coupling simulation method for laser cladding multi-layer and multi-channel forming

The invention provides an ANSYS-based sequential coupling simulation method for laser cladding multi-layer and multi-channel forming, and belongs to the technical field of laser cladding additive manufacturing. In order to solve the problems that the temperature gradient of a heat affected zone and a cladding zone is large and internal stress exists due to the fact that casting defects are repaired through existing laser cladding, the influence of laser power and scanning speed on a temperature field and a stress field of a multi-layer and multi-channel cladding model is determined through a full-factor analog simulation test; and laser cladding process parameters are further optimized to obtain an optimal parameter combination. The simulation method provided by the invention better conforms to the actual repair process, the screening parameters are accurate, the method is convenient and fast, and theoretical support can be provided for actual laser cladding high-quality repair of casting defects. 本发明提供了一种基于A
