Problems solved by technology

The wheel and rail in the crane is an important structure for the work of this carrier, and its operation under complex working conditions will increase the degree of wear between the wheel and rail, which in turn will cause some major safety hazards
[0003] At present, most of the prediction researches on the wear degree of crane wheels and rails at home and abroad are based on the measured stress of the structure under macroscopic conditions, and do not fully consider the composite mechanism of the residual stress inside the material on the wear degree of the wheels and rails.

Embodiment Construction

[0025] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] Please refer to figure 1 , the present invention is a crane wheel-rail wear monitoring method based on residual stress influence interval correction, and the method comprises the following steps:

[0027] S1. Measurement of the macroscopic stress of the wheel-rail structure under the actual working conditions of the crane:

[0028] Firstly, the finite element analysis model of the crane wheel-rail structure is established in the finite element analysis software ANSYS, and the grid is divided by using the adaptive mode, and then the load and constraint conditions of the working condition are imported into the pre-processing module. Start the post-processing process, determine the vulnerable parts of the crane wheel-rail structure in...

Abstract

The invention discloses a crane wheel rail wear monitoring method based on residual stress influence interval correction. The method comprises the following steps: S1, measuring macroscopic stress ofa wheel rail structure of a crane under actual working conditions; s2, measuring the residual stress of the wheel rail structure of the crane under the actual working condition; s3, solving a residualstress influence interval in the monitoring time; s4, calculating composite stress based on residual stress influence interval correction; and S5, calculating a wear value in the crane wheel rail structure based on residual stress influence interval correction. The method is high in detection precision, and has important practical significance in real-time monitoring of crane wheel rail wear.

Description

technical field [0001] The invention relates to crane wheel-rail wear monitoring, in particular to a crane wheel-rail wear monitoring method based on residual stress influence interval correction. Background technique [0002] With the rapid development of economy and society, the usage of lifting equipment has also increased dramatically. Behind the huge crane volume, the safety issues during its operation have attracted more and more attention at home and abroad. The wheel and rail in the crane is an important structure for the work of this carrier, and its operation under complex working conditions will aggravate the degree of wear between the wheel and rail, which in turn will cause some major safety hazards. [0003] At present, most of the prediction researches on the wear degree of crane wheels and rails at home and abroad are based on the measured stress of the structure under macroscopic conditions, and do not fully consider the composite mechanism of the residual ...
