PURPOSE:To provide the motion analyzing method which enables modeling corresponding to the various kinds of grains in special forms and further can analyze the movement, deformation and orientation of those grains in the case of analyzing the motion of grains in fluidized substrate by using computer simulation. CONSTITUTION:Spheres set bodies 1A and 2A mutually coupling plural spheres in a one-dimensional, two-dimensional or three-dimensional direction so as to get the entire form similar to the form of grains are used as models for analysis, the motion of the entire sphere set bodies 1A and 2A is calculated by calculating the parallel advancement and rotation of the respective spheres while applying the degree of freedom for a prescribed coupling length and a coupling angle mutually among the respective spheres, and the movement, deformation and orientation of grains are analyzed from the calculated result. The grains can be modeled as the sphere set bodies 1A and 2A in the approximate form regradless of the shape of grains, and the movement, deformation and orientation of grains can be analyzed based on the calculation of the parallel advancement and rotation of respective spheres. |
