Through the analysis of three-dimensional hub model by using finite element, detailed stress distribution is obtained. On this basis, the dangerous sections of structural discontinuity regions are made stress analysis and classification by using stress linearization method, the stress evaluation is carried out through using design by analysis theory. The results show the structure is safe and reliable.
ANSYS/LS-DYNA finite element software is applied to analysis shocking simulation for washing machine and its packaging with different postures (surface, edge) and different dropping heights. The yielding critical dropping height of suspender is obtained. The response acceleration curves, effective stress and plastic strain cloud fringe distribution on washing tub and shell are also available. The...
Aimed at structure retrofit of sprocket shaft, combining with the practical working conditions, theoretical calculation, finite element method (FEM) Analysis and model test are applied in research. The results show, numerical value of traditional mechanical algorithm is relative small, FEM can express the influence of actual structure, and results are more reliable. FEM Analysis represents stress...
Solid garbage crusher is one of the most important equipments in garbage coal production line. Faults of solid garbage crusher have great influence on the efficiency of garbage coal production line. To solve the problem, an improving design of solid garbage crusher is presented. The key factors that cause the faults to crusher are confirmed through the stress computation of cutting tools. An improving...
