Crane wheel rail wear monitoring method based on residual stress influence interval correction

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 ...

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.
