For the problem of fatigue damage that occurs easily in the right-angled structure of bridge cranes, the stress influence of the right-angled structure is analyzed with Ansys. In this paper, the right-angled structure of bogie for the bridge crane is as the research object, and its FEA model is built with plate elements. After sensitivity analysis, the factors influencing stress are determined. According to the stress influence sequence, the trends between these factors and the stress are studied respectively by response surface method (RSM). Then, an agent model, that considers the overall structure and integrates the multi-factors effects, is built to enhance the efficiency of stress calculation for right-angled structures.

摘要

For the problem of fatigue damage that occurs easily in the right-angled structure of bridge cranes, the stress influence of the right-angled structure is analyzed with Ansys. In this paper, the right-angled structure of bogie for the bridge crane is as the research object, and its FEA model is built with plate elements. After sensitivity analysis, the factors influencing stress are determined. According to the stress influence sequence, the trends between these factors and the stress are studied respectively by response surface method (RSM). Then, an agent model, that considers the overall structure and integrates the multi-factors effects, is built to enhance the efficiency of stress calculation for right-angled structures.
