Paper Title:
Modelling Methods and Error Analysis of Deformable and Non-Deformable Real Particles
  Abstract

In order to realize the real particles’ irregular shape representations, which considering the real particles’ deformable and non-deformable characteristic. Firstly, we extracted the three dimensional coordinate information of real ballasts by dealing with ballast’s X-ray tomography imagines. Secondly, considering the deformable and non-deformable characteristic, two mdoelling methods were introduced based on real particles’ three dimensional coordinates. The deformable particle models are generated by non-overlapping combined basic-spheres, while the generation process is controlled by the extraction accuracy of real particles’ three dimensional coordinates. The non-deformable particle models are generated by overlapping combined basic-spheres, while the generate process is controlled by two parameters. Both two modelling method are initial conditions unrelated, and the model generation process can be repeatedly. Finally, in the condition that two methods’ basic-sphere numbers are approximately equally, the conclusion that non-deformable modelling method represents the real particles’ shape more efficiently can be drawn by error analysis.
