跑道模拟靶板石块分布模型生成方法

The Generation Method of Airport Runways Simulated Target Plate's Stones Distribution Model

针对机场跑道模拟靶板中石块分布模型存在差异性的现象,以随机投放和角度排序理论为基础,提出了跑道模拟靶板石块分布模型生成方法。该方法借助ANSYS软件,通过蒙特卡洛法进行圆形石块随机投放生成基圆,接着使用角度排序理论生成单一"凸"多边形石块,然后生成跑道模拟靶板的面层和基层,最后生成二维跑道模拟靶板石块分布模型。实例表明,该方法成功生成跑道模拟靶板石块分布模型,所模拟石块的分布和石块形状呈现随机分布性,弥补了以往方法在模拟石块形状多样性方面的不足。参数化的石块分布模型可以实现直接与多数显式动力学仿真软件衔接。

According to the differences phenomena between the airport runways simulated target plate＇s stones distribution models.Based on the random delivery and angle order theory,one generation method of airport runways simulated target plate＇s stones distribution model was proposed.The method depending on the ANSYS software,first circular stones were generated randomly on the base circle through the Monte Carlo method,and then with the help of angle order theory,a single ＂convex＂ polygon stone was generated,and then the surface and base of airport runways simulated target plate were generated,and finally two dimensional simulated target plate were generated.Example showed that simulated target plate rocks the runways distribution model were generated successfully with this method,the distribution and the shape of the simulated stones displayed random distribution features,which made up the shape of the conventional method in a simulated stones diversity gaps.Parametric distribution model stones could communicate directly with the explicit dynamics simulation software convergence.
