水下多层异质材料激光热熔切割的工艺仿真研究
Simulation study on underwater laser fusion cutting of multi-layer heterogeneous materials
摘要
Abstract
Laser underwater cutting technology,with its advantages of adapting to confined spaces,high density,and minimal heat input,can overcome the shortcomings of conventional mechanical methods.It offers the feasibility of efficient and clean processing,and thus holds broad application prospects within the nuclear industry.In this paper,the simulation method is utilized to simulate the underwater cutting of a stainless steel-alumina multiphase flow model,investigating the effects of three cutting parameters-laser power,cutting speed and heat source radius-on the risk of leakage from the inner layer of alumina material.The simulation results were fitted and analyzed to explore the combined influence of laser power and cutting speed on the leakage risk of the inner layer of alumina material.The results indicate that when the other two parameters are constant,the increase of laser power will increase the risk of leakage of the inner layer of alumina material.The increase of laser cutting speed will also increase the risk of leakage of inner layer alumina material;However,the laser radius has little effect on the risk of alumina leakage in the inner layer.Under the combined action of these two variables,the high laser power and small cutting speed will reduce the leakage risk of the inner layer of alumina material.The work done in this paper can analyze the important influencing factors and trend relationships in the cutting process of underwater multilayer heterogeneous materials,so as to reduce the experimental workload and save costs.关键词
