论文摘要
提出了一个基于MATLAB的计算过程，以用\ verb | matlab |支持的任何指定概率分布随机挑选出半径的球体。提出了填充单位立方体的一般程序序列和示例，平行静音和两个半球形表面之间的凹面域，带有从威布尔和伽马分布中绘制的半径的球。考虑到粉末床3D打印过程中激光束加热的颗粒之间的键形成的样品模型。
A Matlab-based computational procedure is proposed to fill a given volume with spheres whose radii are randomly picked from any specified probability distribution supported by \verb|Matlab|. The general program sequence and examples of filling a unit cube, a parallelepiped, and a concave domain between two hemispherical surfaces, with spheres whose radii are drawn from the Weibull and Gamma distributions, are presented. A sample application to the numerical modeling of bond formation between particles heated by a laser beam in powder bed 3D printing process is considered.
