29 Jun 447: Hard Top Mould Linear static stress and linear buckling analysis of a hard top mould for a yacht. Multiple load cases were analysed for both stress and buckling analyses, with the mould being held in different orientations, as well as being suspended or on trunnions. The Factor of Safety was reported for all the stress analyses, and the first buckling load multiplier for the buckling analyses. Posted at 11:00h in Read More
29 Jun 448: Pulley Box Linear static stress analysis with non linear contact of a pulley box assembly. A half model was used for the analysis as the geometry and loads were symmetrical. The minimum factor of safety on yield strength was reported for each part, highlighting areas where design changes should be made. Posted at 11:00h in Read More
29 Jun 450: Chain Plate Assembly Fully non-linear stress analysis of chain plate assembly, subjected to a gradually increasing tensile load. The results showed that the chain will fail well before the intended breaking load, and hence saved expensive prototyping and physical testing. Posted at 11:00h in Read More
29 Jun 453: Ring Assembly Static stress analysis with non-linear material models and non-linear contact of a ring assembly, using a half model. Two different load cases were analysed, with a different steel grade being used in each case. The purpose of the analysis was to find the ultimate vertical load that the ring assembly could withstand before failing, and this was reported in both load cases. Posted at 10:59h in Read More
29 Jun 454: Small Hook Linear static stress analysis of a small hook design, using a non linear material model. The hook was subject to a straight lifting load, which was gradually increased. The load, where the stress reached the ultimate strength was reported as the maximum load before failure. Posted at 10:58h in Read More
29 Jun 455: Buoy Alteration Linear static stress and modal analysis of a buoy. Several designs were analysed, with the inclusion of different parts, gussets and patches in each. Different stress load cases were analysed with different accelerations applied to the buoy. The minimum factor of safety was reported for each load case, as well as the first natural frequency from the modal analysis. Posted at 10:58h in Read More
29 Jun 457: Buoy Linear static stress analysis and a modal analysis of a buoy. The stress analysis consisted of 4 different load cases, with different applications of different acceleration loads. The modal analysis indicated which components of the design influenced the natural frequencies of the assembly the most. The stress analysis highlighted potential areas of concern in the model which required modification. Posted at 10:58h in Read More
29 Jun 459: Lightweight Buoy Linear static stress analysis with non linear contact, and a modal analysis of a buoy. The stress analysis consisted of 4 different load cases, with different applications of different acceleration loads. The modal analysis indicated which components of the design influenced the natural frequencies of the assembly the most. The stress analysis highlighted potential areas of concern in the model which required modification. Posted at 10:57h in Read More
29 Jun 463: Exchanger Steady state heat transfer, linear static stress, and linear buckling analysis of an exchanger design. The maximum allowable stress values for the static stress analysis were taken from standard ASME Section II D, which the model passed, although the recommendation was made to include environmental loads such as wind to ensure the design was strong enough for operation and to pass the required standards.

29 Jun 181: Tank Linear static stress and linear buckling analysis of a tank. For the initial design, 3 load cases were analysed; One evaluating stresses due to the tank being lifted, and 2 due to hydrostatic pressure applied in different ways. In each of these stress load cases, a buckling analysis was also performed. A second design was also analysed as the stresses in the initial design were too high. Recommendations were made to improve the design. Posted at 10:57h in Read More
