A Bearing Fatigue Life Prediction Method for Huge Ring-hugging Tire Unloading Machine

Abstract

The invention discloses a bearing fatigue life prediction method of a ring-hugging giant tire unloading machine, which is used for predicting the fatigue life of the bearing at the rocker arm of the tire unloading machine and the bearing at the guide rail wheel. The present invention combines dynamics, statics, and fatigue life simulation software to simulate and analyze the rocker arm of the tire unloader and the bearing of the guide rail wheel, which is simple, reliable, time-saving and labor-saving, suitable for engineering applications, and fills the current gap for giant tire unloader bearings There is a gap in the field of fatigue life research; use dynamics, statics, and fatigue life prediction software commonly used in the engineering field to predict the fatigue life of bearings, and the analysis results are relatively scientific, providing relevant theoretical support for the mechanical characteristics and safety of use of bearings.

Description

technical field [0001] The invention belongs to the field of tire unloaders, and particularly relates to a bearing fatigue life prediction method of a ring-enclosed giant tire unloader. Background technique [0002] At present, with the rapid development of heavy machinery, the tonnage of tires used in heavy machinery has also increased rapidly, and giant tire unloaders have also emerged. During the working process, there will be impact due to collision and movement, which will cause the system to vibrate strongly, and the bearing force in key parts will also be very complex. Complex working conditions can easily cause bearing failure. SUMMARY OF THE INVENTION [0003] In order to solve the deficiencies in the prior art, the present invention aims to provide a bearing fatigue life prediction method of a ring-enclosed giant tire unloader, so as to provide relevant theoretical support for the mechanical characteristics and use safety of the bearing. [0004] To achieve the ...

Problems solved by technology

[0002] At present, with the rapid development of heavy machinery, the tonnage of tires used in heavy machinery has also increased rapidly, and the giant tire unloading machine has also emerged as the times require. When the tire unloading machine is working, the mass of the giant tire clamped can reach 6 tons, and there is a large inertia During the working process, impacts will be generated due to collisions and movements, which will cause strong vibrations in the system, and the bearings in key parts will also be very complicated in stress, and complex working conditions can easily cause bearing failure.
