Based on the test about compression-rebound properties of material bed, there are three zones in roller mill. The movement of material bed between two rollers in roller mill has been analysed. The pressure distribution equations in every zone on the roller's surface have been derived. The stress in roller is important for roller's failure analysis and the life estimation. But it depends on load, structure...
The piled wharf on slope may impacted by the deformation of soft soil foundation, the lateral displacement of pile cap would increasing because the deformation of soft foundation, which would threaten the safety of wharf structure. The creep is one of the important factors, so it is meaningful to research the creep characteristics of slope. In this paper, the deformation damage of piled wharf and...
The forces of the ship-based helicopter are analyzed comprehensively in the winds and waves. The parameterized FEM model about the ship-based helicopter body, the mooring cable and the mooring base is established with the language APDL. The parameterized FEM model is used to calculate the tension of the mooring cables for different sea conditions. The mooring cable will present strong nonlinearity...
