Modal, response spectrum analysis (RSA), and a linear static stress analysis of a separation tower, using a plate element model. One design was analysed, with multiple static stress load cases considered, including environmental loads such as wind loads which were calculated by FEA-Solutions. For the modal analysis, the modes and the mass participations were reported. For the RSA and stress analyses, the maximum stress within the assembly was reported.
Modal, response spectrum analysis (RSA), and a linear static stress analysis of a distillation column, using a beam element model. 3 designs were analysed, with the first 2 only being subject to the modal analysis and RSA. The third design was subject to these analyses, but also multiple static stress analyses with different load cases with varying loads, including environmental loads, such as wind. For the RSA and stress analyses, the stresses were reported.
Linear static stress analysis of a seat box and support for a lifeboat seat, subjected to several load conditions. 2 Designs were analysed for the box and support. For the box, composite elements were used to model the components made from GRP. Stresses observed in the models were reported. Recommendations were given on design improvements.
Linear static stress of a hypobaric chamber assembly, using plate elements to represent the geometry. The model was subject to a vacuum pressure. The stresses from the model showed that although the majority of the model experienced low stresses, areas of concern included corners of internal framework and the window frame.
Linear static stress analysis of a spindle, subject to different centrifugal loads. Different rotational speeds of the spindle were analysed with results compared to real operations where failure occurred. The results of the FEA corresponded with the real-life failure showing high stresses in the same areas as the failure occurred.
Modal and linear static stress analysis of a lens assembly. In total the first 5 natural frequencies and modes were analysed for 9 different designs, with various changes to the plate thicknesses in various components considered. For the final design reported, the stresses in the assembly due to dead weight were also analysed, and it was found to have stresses well below the yield strength of the materials used.
Modal and shock (transient stress) analysis of a Cabinet design. The modal analysis was completed as a prerequisite for the shock analysis. The load considered for the shock analysis was a 30g half sine wave pulse of 25ms. The peak stresses in the model were reported.
Linear static stress analysis with non-linear contact of a strake and ring assembly. Two different models were analysed, with different welding designs, both being subject to an internal pressure. A 9 degree pie cut model was used for both models. For one of the analyses, the fatigue life was calculated in accordance with standard PD5500.
