有限元分析法在挖掘机工作装置分析中的应用

摘要

将有限元分析法应用在液压挖掘机的工作装置中。分析了挖掘过程中承受的交变复合外力，以及工作装置的强度和变形情况；从而更好地了解动臂和斗杆是否坚固可靠，用以指导结构改型，使其设计更加合理。%The finite element is applied in the excavator working device analysis in this paper. The inter-variable composite force in its exca⁃vating process, its intensity and distortion are analysed to better know if the boom and arm in the operation are in stability, and can guide the remodel of structure, to make its design more reasonable.
