Abstract Details

1992, Doctor of Philosophy, Case Western Reserve University, Mechanical Engineering.
Experimental and finite element stress analyses were conducted on the mixer blades and hub of an impeller. The correlation between the experimental and finite element model results was fairly good. The operation process of filling-draining-refilling the liquid tank has enormous impact on the dynamic stresses in the blades. Design studies showed that the bending stresses at critical locations of the blades can be significantly reduced by eliminating the stress concentration at those critical locations through redesign of the hub and gussets without significantly increasing the manufacturing cost. The residual stress on the outside surface of the Hi-Flow blades induced by the forming operation can be minimized by using the double forming operation. Consequently, the fatigue lives of the high flow blades can be significantly extended.
