Abstract: | A closed loop servo-hydraulic structural fatigue testing machine was developed. It can apply fatigue loads on actual engineering
parts or components for their fatigue strength evaluation. The testing machine consists of a structural bending load frame,
a structural torsion load frame, a hydraulic system, and a control system. Stress analysis and design for the crosshead, columns
and test bed for the structural bending test frame are described. Finite element analysis was performed for the structural
torsion load frame. Evaluation of the structural load frames and application of the test machine are briefly given. |
