29 Jun 160: Mounting Frame Linear static stress analysis of a mounting frame for various equipment, including components lashed to the frame. Non linear surface contacts were used in the analysis. 4 different load cases were analysed, with different acceleration loads being applied to the assembly. Stresses were reported as being below yield for every load case, with the lashing forces also reported. Posted at 11:44h in Read More
29 Jun 290: Rudder Spider Linear static stress analysis with non linear surface contact of a rudder spider design. 3 design iterations were analysed in total, with each iteration analysed with the rudder in two different positions. The high stresses which were well above the allowables on the initial design, were eradicated by the final design due to the recommendations provided. Posted at 11:43h in Read More
29 Jun 022: Pallet Linear static stress analysis of a pallet design, including equipment being mounted on the pallet itself. Multiple load cases were analysed, with the assembly being subject to a lifting acceleration, and acceleration in 6 other directions. On review of the results, design modifications were recommended due to insufficient lashing of the equipment to the pallet. Posted at 11:43h in Read More
29 Jun 368: Gangway Linear static stress with non-linear contact and linear buckling analysis of a gangway. Initially the design was analysed subject to a live load and a wind load. The same design was then analysed with a reduced wind load, and was then analysed using different dimensions for the SHS used. A more detailed analysis on just the end frame of the gangway was recommended and then carried out. 4 design iterations of the end frame were completed, with the final design having acceptable Factor of Safety values.

29 Jun 019: Hoist boom rig Linear static stress analysis of a boom rig, analysed with the boom in different positions, subjected to dead weight. Beam elements were used to represent the model. Beam stresses were reported for each load case, with low stresses seen throughout the assembly, well below the yield strength of the material. Posted at 11:43h in Read More
29 Jun 405: Boat Seat Static stress analysis with non-linear material model and non-linear geometry (large deformation) analysis of a seat for a boat. Initially the analysis was just a linear static stress analysis, but on review of the results a non-linear material model was included, and then large deformation. The stress and plastic strain observed in the model decreased with the inclusion of a non-linear material model and large deformation. Posted at 11:42h in Read More
29 Jun 410: Polaris Vacuum Tank Half model of a large vacuum tank for a research project. Three design iteration have been analysed, each implementing modifications based on the FEA results of the previous version. Extensive physical testing on the completed vessel confirmed that the analysis was correct. Posted at 11:42h in Read More
29 Jun 011: Umbilical Termination Assembly (UTA) Linear static stress analysis of a UTA, using non-linear contact. A half model was used for the analysis, with solid and beam elements being used to represent the geometry. 2 Load cases were analysed with different pulling forces being applied to a component on the model. Design changes were recommended. Posted at 11:41h in Read More
