Dynamic Simulation Method of Bulldozer Tilting Mechanism

Abstract

The invention relates to a method for dynamics simulation analysis of a tilting mechanism of a bulldozing blade. The present invention uses a lever mechanism to replace the left and right lifting cylinders in the traditional tilting dynamics model of bulldozing blades, so that the dynamics model truly realizes the tilting motion only by the driving of the tilting cylinder; by checking the displacement curve of the hinge point of the lifting cylinder To check whether this method meets the kinematic requirements; through experimental measurement or theoretical calculation of the force of the hinge point to check whether this method meets the mechanical requirements. The method provided by the invention more follows the tilting principle of the bulldozing blade; the calculated simulation result of the tilting dynamics of the bulldozing blade is more accurate.

Description

technical field [0001] The invention belongs to the field of dynamic simulation analysis methods, and in particular relates to a dynamic simulation analysis method of a bulldozing blade tilt mechanism. Background technique [0002] The bulldozer blade is the main working device of the bulldozer. It is mainly used for leveling the site, backfilling the foundation pit, removing obstacles, clearing snow, and shoveling and accumulating loose materials within a short distance. Complex and changeable working conditions determine that the bulldozer blade can complete combined actions such as lifting, lowering, tilting and even angle adjustment. It is an important work to optimize the structure of the bulldozer blade and improve product quality to study the force changes of the bulldozer blade during the lifting, lowering, tilting, and angle adjustment.

AI Technical Summary

Problems solved by technology

[0008] (1) When performing the simulation analysis of the tilting dynamics of the bulldozing blade, it is necessary to add an additional drive to the lifting cylinder, which is inconsistent with the actual tilting principle of the bulldozing blade;

[0009] (2) The difference in force between the left and right lifting cylinders is too large, which does not follow the actual force law of the lifting cylinder;

[0010] (3) The simulation analysis results are inaccurate and the error is large
