  • Publication number: 20200394347
    Abstract: A method for assessing fatigue damage and fatigue life based on Abaqus is provided. The micro-macroscopic scale coupled model is based on the macroscopic representative area and the microstructure characterization of the material, and the microscopic sub-model is established by the Voronoi algorithm. The algorithm has good cross-platform compatibility and portability, fundamentally solves the technical problem of micro-macroscopic multi-scale coupling and establishes and applies the multi-scale coupled model to the fatigue damage and life assessment. The micro-macroscopic multi-scale coupled fatigue damage and life assessment model and algorithm of the material is capable of both considering the fatigue damage evolution on a microscopic scale and assessing the fatigue life, as well as calculating and assessing the two physical parameters on a macroscopic scale, so as to predict the fatigue damage and life of the whole workpiece.

  • Publication number: 20200394348
    Abstract: A method for assessing fatigue damage and a fatigue life based on a crystal plastic welding process model. According to the new method, consideration is given to the effects of the crystal slip system and the polycrystal plastic strain on the welding process performance of the material. A welding process damage and fatigue life assessment model is established on the mesoscopic scale. The effect of microscopic characterizations of materials on the welding process performance, as well as on the fatigue damage and life of welded joints, can be studied from the mesoscopic point of view. The relationship between the welding process and the evolution of the material performance can be determined by the macro-mesoscopic coupling calculation model to further determine the effect and degree of welding processes on the fatigue damage and life of materials.

  • Publication number: 20200266630
    Abstract: A physical address determining method, apparatus, and device, and a storage medium, and belongs to the field of solar power generation, includes: controlling at least two slave nodes to sequentially start up, and detecting a change status of an input voltage of the master node; dividing a photovoltaic power generation system into a plurality of photovoltaic strings; and for each candidate photovoltaic string, controlling any slave node located in the candidate photovoltaic string to start up and other slave nodes to shut down, and using the physical address as a physical address of the candidate photovoltaic string. This disclosure provides a manner of automatically determining a physical address of a photovoltaic string, thereby implementing photovoltaic-string locating and expanding a system function range. When an anomaly occurs, the anomaly can be eliminated in a timely manner, thereby improving system stability.
