In this paper, the deformation, internal forces and stress of single throttle slice of shock absorber was analyzed, the formula of the stresses of its were established. Studied the pressure and the stresses on each slice, the analytic stresses formulas of multi-slices were established. Followed a practical example for stresses computation of multi-slices with this new analytic method, and it was simulated...
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...
Combination and simplification are often adopted as the solution to the problem of there are lots of the Crack group, Pore group and Inclusion group in the components especially in welded joints. In this study, simplifications were simulated with CAE software. The comparison results dedicates that the Stress Intensity Factors (SIF) obtained after simplification were greater than the primary. Therefore,...
