摘要

The scraper is the core of the conveyor and its vulnerable part. The problem of bending fracture of common welding scrapers in actual production is under consideration. SolidWorks and ANSYS finite element analysis software were used to construct the three-dimensional model for simulation analysis, and the existing structure was improved and optimized. The comparison results showed: well-type stiffener contributes to improvement of the overall strength and rigidity of the scraper. Before optimization, the maximum equivalent stress on the press buckle part of the scraper was 310 MPa, and after optimization it dropped to 230 MPa, i.e., decreased by 26%, and the stress value of one side of stiffener was 170 MPa, with certain bending resistance. After optimization, the stress distribution of the scraper was uniform, with solving the problem of stress concentration. After optimization, the overall safety factor of the scraper increased by nearly 15%, improving its life. Integrity of the optimized scraper was nearly 100%, as compared to that before optimization under the same conditions, which confirmed the validity of scraper optimization.
