AI Technical Summary

Technical Problem

Existing simulation methods fail to fully consider the differences in the contact areas between the tires and the weighing body of multi-axle heavy mining vehicles and the uneven distribution of loads, resulting in discrepancies between simulation results and actual conditions. This makes it difficult to accurately assess the stress state and deformation of the weighing body, affecting the accuracy of structural optimization design and life assessment.

Method used

A refined finite element model of the vehicle-weighing system was established. By distributing the load according to the actual contact area of ​​each tire, the full load and off-center load conditions were realistically simulated, and the stress distribution and deformation data of the weighing system were obtained. A modeling strategy combining shell element mid-surface processing and geometric idealization was adopted to accurately obtain key mechanical parameters.

Benefits of technology

It significantly improves the realism and accuracy of simulation results, provides a reliable basis for structural strength verification, and provides data support for fatigue life assessment and maintenance cycle formulation of the scale body through comparative calculations of full load and off-center load conditions, forming a complete data chain.

Abstract

The application discloses a simulation calculation method for a mine truck scale, and belongs to the technical field of scale simulation. The method comprises the following steps: a three-dimensional geometric model is established according to an assembly drawing of a truck and a scale body and is subjected to idealization treatment; a finite element model is constructed based on the idealized geometric model, including geometric flaw preprocessing, mesh division, material and thickness assignment and integration verification; boundary conditions are set according to an actual working state, and loads are distributed and applied according to actual contact areas of tires for full-load working conditions and partial-load working conditions; displacement distribution and stress distribution of the scale body under the two working conditions are calculated and analyzed respectively, and whether the scale body meets the design range and material strength requirements is judged. Through fine distribution of the whole vehicle load according to actual contact areas of each tire, the application can truly simulate a force field of the mine truck scale under complex working conditions, accurately obtains stress distribution and deformation data, and provides reliable data support for structural design optimization and life evaluation of the scale.
