Rock Box FEA Analysis & Re-Design
The rock box was tasked with withstanding a peak pressure of 500kPa without deforming.
Utilising a surface model, a linear-static FEA was conducted. The FEA concluded that the initial design was not suitable to withstand the peak pressures induced by the dredge. The results are displayed below. All areas displayed as grey can be considered as deformed.
The results from this FEA verified that the original geometry plus the addition supports were not satisfactory to withstand the induced peak pressures. Therefore, a re-design of the rock box was suggested that was more complementary to standard pressure vessel geometry.
The re-design of the rock box is displayed below.
