Structural Failure Analysis of Shaft of Wobbly and Attrited Testing Equipment
In order to research the fatigue strength of gasket which is with new composite material in one plane, we designed and manufactured special testing equipment. The material of shaft of testing equipment is 30CrMnSi. In the experiment, the 30CrMnSi shaft was broken into two parts by suddenly. By structural analysis, static analysis and heat treatment analysis for shaft, we get the reason of fracture for shaft finally. The problem solved make the test goes well and can help design and manufacture testing equipment in the future.
