The frequencies for free rings have been studied by many authors. But there appear few literatures which deal with the vibrations of rings considering any stiffened conditions. Present report developed experimentally the natural frequencies of circular rings subjected to radial load sets. Forty-six steel rings were investigated; whose rim cross sections were rectangular; ratio of rim thickness to radius of curvature of center line of rim h/r 0.029∿0.128; width of rim b 8.1∿100.0mm. These samples were stressed in tension subjected to radial two or three loads and were vibrated by shaking apparatus. Then their natural frequencies of rings were measured. Increasing tension loads, the natural frequencies of rings were larger and larger. So the relationship between tension loads and the natural frequencies of rings were expressed by one experimental equation.
