29 Jun 106: Pan and Tilt Assy Linear static stress and linear buckling analysis of a Pan and Tilt assembly, subject to external pressure. All three element types (beam, plate and solid) were used in the analysis. Although the design passed the acceptance criteria for the buckling analysis, the factor of safety requirements were not met. As a result, recommendations were given to improve the design in a number of areas. Posted at 09:55h in Read More
29 Jun 103: Telescopic Mast Non-Linear Finite Element Analysis of Telescopic Mast assembly, evaluating displacements of antenna and guy wire forces at given wind speeds, with the wind acting in different directions across multiple load cases. 2 designs were analysed, one with the top segment of the telescopic mast being made from GRP, and not Aluminium. The maximum deflections of the assembly were reported, as well as the allowable loads for the guy wires constraining the mast. No mast buckling was reported during the analysis, which was evaluated up to twice the design load. Posted at 09:55h in Read More
29 Jun 101: Mast Assembly Non-Linear Finite Element Analysis of Mast assembly, evaluating displacements of antenna and guy wire forces at given wind speeds, with the wind acting in different directions across multiple load cases. The maximum deflections of the assembly were reported, as well as the allowable loads for the guy wires constraining the mast. No mast buckling was also reported during the analysis, up to twice the design load. Posted at 09:54h in Read More
29 Jun 097: Fork Pin Assembly Linear-Elastic static stress analysis of a fork pin assembly, with non-linear contact. The model was subject to axial forces on the pin and table. A quarter model was used for the analysis. The results highlighted potential areas of concern in the design, although the majority of the components passed the acceptance criteria.

29 Jun 095: Housing and Cap Linear-Elastic static stress analysis of a housing and cap model, with non-linear contact. The model was subject to an external pressure. Upon completion of the analysis, the design was revised twice before the model passed the acceptance criteria. The final design was also subject to a linear buckling analysis which confirmed that failure would not occur due to buckling. Posted at 09:52h in Read More
29 Jun 093: 90m Instrumentation Mast Non-linear dynamic analysis of a rather complex guyed mast subjected to a linearly increasing wind speed. Spreadsheet calculations have been used to establish the wind loads which are depending on height and Reynolds’s number. Posted at 09:52h in Read More
29 Jun 090: Lifting Frame Linear-elastic static stress analysis of a lifting frame for an inflatable boat. Three different parts of the overall assembly were analysed. For two of the parts, mirror symmetry models were used. For the part that failed the acceptance criteria, changes to the design were implemented with the modified design passing the acceptance criteria. Posted at 09:35h in Read More
29 Jun 089: Link Plate Linear-elastic static stress analysis of a link plate assembly, including non-linear contact, subjected to a tensile load. A quarter model was used for the analysis. Due to the nature of the contact between the link plate and the chain link, it was recommended to re-run the analysis with a non-linear material model. Posted at 09:34h in Read More
29 Jun 087: Daylight Profile Transient Heat Transfer analysis and non-linear static stress of a light, using a 2D model. The heat transfer analysis results were used as inputs for the stress analysis. Temperature dependent material properties were used for the stress analysis, to ensure the results at elevated temperatures were correct. Despite the stresses being below the maximum allowable stress value, recommendations were given to run the model with different loading conditions which hadn’t been considered.
