The analyses indicated a structurally sound design with each SHSS frame section by comparison to acceptable limits for structural deflection and strength code.
The worst case scenario using two 1700mm-longest structural elements of the frame treated as simply supported with half- weight of the tank uniformly distributed on each was used in the analyses. Operational deflections and stresses in the frame structures were analyzed using effective elasticity formulae with each SHSS section for overall integrity assessment of the agitator in service. Three square hollow structural steel (SHSS) frame sections of 60圆0mm, 50x50mm, and 40x40mm and 3mm wall thickness were selected for the structural elements. The agitators feasible frame configuration and structural specifications were conceptually designed for supporting the paint tank with angle inclination of 22° in continuous rotation through 360o during the agitation time. Basically, the agitator was designed to consist of a steel supporting frame structure for the tank and a 50mm-diameter-90mm-long steel shaft gear-driven with a torque of 1800Nm by a 4-Hp electric motor.
