Abstract

The invention provides a structure surface wear simulation method based on a discrete element method. The structure surface wear simulation method includes the following steps that S1, the structure surface shape is obtained, and a target surface is divided into a triangular mesh composed of a plurality of triangular units; S2, discrete element simulation is conducted on the triangular units, the scattered particle collision processes of the triangular units are simulated, and thus the collision energy data of all the triangular units are computed and recorded; S3, the sizes of the materials stripped out of the surfaces of all the triangular units are computed according to the collision energy data obtained in S2, and thus the height variable quantity of the centers of mass of all the triangular units is obtained according to the material sizes; S4, the target surface is fitted again according to the height variable quantity of the centers of mass of all the triangular units obtained in S3. The structure surface wear simulation method based on the discrete element method provides reference for structural design, functional design, service life design and the like of scattered material processing equipment.

Description

technical field [0001] The invention relates to the field of mechanical structure simulation design for bulk boring treatment, in particular to a structure surface wear simulation method based on a discrete element method. Background technique [0002] One of the major failure modes of bulk materials handling machinery is structural surface wear. Surface wear refers to the phenomenon that a large number of gravel, rock, dust or similar loose particles frequently collide with the friction mechanical structure, and cause the volume of the surface material to peel off. [0003] The surface wear mechanism of structural components is complex, which is not only related to the material and working conditions of the material itself, but also the collision process between the scattered particles and the structure in the mechanical equipment is closely related to the collision energy. Therefore, the current theoretical research on the surface wear of structures There are high technic...
