| Scraper is the main working part of garbage collection in the rear loading compressed garbage truck, and the stress deformation has large influence on working performance of the vehicle. In order to realize the lightweight design, based on the analysis of the force of the scraper, the simplified model is established by NX and ANSYS software, and the stress and strain nephogram are obtained by dividing the mesh and adding the load and the constraint. By analyzing the stress and strain nephogram, the maximum strain of the scraper appears in the middle of the lower half of the scraper, and the maximum stress appears at the indirect joint of the parts. Therefore, through the uneven arrangement of the stiffened plate, the weight reduction on both sides of the scraper and the enhancement of the welding quality at the joint of the pressboard, it is of great benefit to the optimization of the scraper structure, thereby saving the cost of the enterprise and enhancing the competitiveness. |
