Abstract

The invention discloses a vibrating screen surface dynamic load optimization method, which comprises the following steps of: 1, selecting a design variable, and establishing an experimental matrix; 2, carrying out a response curved surface experiment; step 3, establishing two double-objective optimization models and solving the two double-objective optimization models; obtaining two groups of Pareto solution sets, wherein the solution sets respectively represent the screening efficiency optimization path of the vibrating screen under the conditions of high screen surface dynamic load and low screen surface dynamic load; and 4, calculating the screen surface dynamic load optimization space under the high screening efficiency. The screen surface dynamic load can be directly reduced, the overall structural load of the screening machine is indirectly reduced, and the service life of the screen surface and the whole vibrating screen is prolonged.

Description

technical field

[0001] The invention belongs to the technical field of mechanical equipment and relates to a vibrating screen, in particular to a dynamic load optimization method for a vibrating screen surface. Background technique

[0002] The vibrating screen works by using the reciprocating rotation vibration generated by the vibration of the vibrator. The upper rotating weight of the vibrator causes the screen surface to produce plane circular vibration, while the lower rotating weight causes the screen surface to produce conical rotary vibration. The vibration amplitude can be changed by adjusting the excitation force of the upper and lower rotating weights. And adjusting the spatial phase angle of the upper and lower weights can change the curve shape of the motion track of the screen surface and change the motion track of the material on the screen surface.

[0003] The vibrating screen separates the granular materials according to the particle size through high-fre...
