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...
