Linear static stress analysis with non-linear contact of a cable spreader, subjected to working loads. 3 different configurations were analysed of the design, each using a half model. Upon completion of the analysis recommendations were made to modify the design to to reduce the stresses.
Linear-elastic static stress analysis with non linear surface contact of a buckle assembly, using a quarter symmetry model. Stress and displacements were reported for the design, showing that the stresses in the model were well below the yield strength of the material.
Linear elastic static stress analysis of a collector tank, subject to dead weight, hydrostatic pressure and internal pressure. The acceptance criteria were not met, so modifications to the design were recommended, with most locations of failure being local to inner radii in the model.
Non-linear analysis of scraper lip seal, consisting of a metallic spring and an elastomeric seal, subjected to compression between two contact faces. FEA resulted in recommendations given on how to improve the spring and hence increase its life.
Non-linear stress analysis of a barrel assembly. Two analyses were conducted, one analysis being a static analysis, the other transient. A 2D axisymmetric model was used to represent the assembly. The load for the transient analysis consisted of a pressure load history. The maximum stress and the maximum radial gap reported from the analysis were very similar in both analyses, indicating in this circumstance, a static analysis was adequate.
Linear static stress analysis with non linear contact of A380 Recovery Package. 5 designs were analysed in total: Link top and Bottom, Pin top and bottom and a test adaptor. All designs were subject to the same 165ton lifting load, with stresses reported for each component, highlighting areas of interest.
