 用欧拉法对薄壁件激光直接成形建模 Alternative Title Mathematical modeling of laser direct metal forming of thin wall by Eulerian method 张永杰; 虞钢; 何秀丽; 宁伟健; 郑彩云 Source Publication 金属热处理 2011 Volume 36Issue:7Pages:92-95 ISSN 0254-6051 Abstract 采用欧拉方法建立了激光直接成形薄壁件的二维传热模型。分离模型中的参数和变量并对模型进行了无量纲化,对最终无量纲化模型中的6个无量纲参数进行了分析讨论。研究表明:针对此二维传热模型的无量纲化减少了参数,简化分析过程;在激光直接成形过程中,实际层高和光束移动速度的乘积共同对温度场起作用,而非单独影响温度场。 Other Abstract A two-dimensional mathematical model based on Eulerian method was developed to describe the laser direct metal forming of a thin wall.The mathematical model describing the time-varying system was nondimensionalized.The results show that the mathematical model can simplify the analysis and reduce the number of parameters.In the laser direct metal forming process,the product of layer increment and laser travel speed contributes to the evolution of temperature distribution.
