Boom Buckling Instability Capability Studies

Based on the powerful finite element analysis software-ANSYS Workbench co-simulation platform, boom buckling instability capability has been studied by using the seamless interface of DM(Geometry Modeler),Mechanical(Structure Analysis)and DX(Optimization Design)module. Firstly, the trend figure that the thickness of each plate increasing has influenced on the overall buckling limit has been got. Applying the rule, the actual structure was optimized and the optimal combination of thickness was found. Under the condition of the buckling limit, the weight of the crane arm has a significant reduction compared with the actual structure. Finally, this result which is reasonably practicably provides a reference method for engineering mechanism design including large-scale crane arm in the future.
