The first generation beach cleaner SWQ18 is mainly made of carbon steel and the unloaded weight is heavy. In the beach test, it occurred such problems as a high fuel consumption and the wheels tend to sink in sand. From the perspective of lightweight material, based on RADIOSS Finite Element Analysis (FEA) module in Hyperworks, the auto-body’s FE model was built. By setting the material as 6061 aluminium alloy and analyzing its body stress and modal, considered the problems that how the aluminium alloy resist the corrosion from the sea atmosphere and its stiffness and strength as well, the result shows that 6061 satisfies the operating requirements and is applicable to the beach cleaner body and a feasible lightweighting scheme taking cost and performance in account was reached. |
