Abstract
Provided is a method of reconstructing and randomly generating three-dimensional profiles of railway ballast particles. The method focuses on two aspects of accurate characterization and random generation of the railway ballast profiles. The method specifically includes: first, obtaining a lot of railway ballast profile samples to form a railway ballast library, and describing the uncertainty of the railway ballasts as much as possible; introducing a spherical harmonic function method into the three-dimensional profile characterization of railway ballast particles in order to accurately reconstruct the railway ballast particle profiles; and finally, establishing a joint probability density function of a spherical harmonic function spectrum to randomly generate railway ballast particles.
