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

Embodiment

[0043] Taking a certain type of bulldozing blade as an example, using the method of the present invention, the simulation analysis of the tilting dynamics of the bulldozing blade is carried out; by checking the displacement curve of the hinge point of the right lifting cylinder, it is proved that the method meets the kinematic requirements; The force of the lift cylinder, left and right trunnion hinge points proves that this method meets the mechanical requirements. The specific implementation process is as follows:

[0044] 1) According to the tilt mechanism of the bulldozer blade, a dynamic model of the tilt of the bulldozer blade is established, and the kinematics simulation is performed on the model. details as follows:

Abstract

The invention relates to a dynamic simulation method for a dozer blade inclined mechanism. A lever mechanism is used for replacing a left lifting oil cylinder and a right lifting oil cylinder in a traditional dozer blade inclined dynamic model, so that the dynamic model performs inclined movement by not only relying on driving of an inclined oil cylinder. Whether the method meets kinematic requirements is checked by checking a displacement curve of a hinge point of the lifting oil cylinders, and whether the method meets mechanical requirements is checked by measuring through tests or calculating theoretically the acting force of the hinge point. The method follows the dozer blade inclination principle, and calculated dozer blade inclined dynamic simulation results are 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. [0003] Bulldozer blade dynamics model: using virtual prototyping technology and based on the actual bulldozer blade mechanism, a...
