Influence Analysis of Rated Capacity on Stress Level of Portal Slewing Crane Based on Data Mining

Portal slewing crane is used frequently and the working conditions is poor. Rated capacity is the main technical parameter of crane. In this paper, according to different rated capacities, high stress value measuring points are selected by means of statistical test data samples, and the relationship between the overall stress and the rated capacity as well as the distribution law of each position are determined. Furthermore, the stress distribution law of high stress value measuring points and the stress characteristics of each position on cranes with different rated capacities are excavated.
