Abstract: The model of circular spring encircling a rotating smooth metal rod is established. The differential e- quation of displacement is derived by infinitesimal analysis method and the solution is given. The theoretical expres- sion of total length of spring in rotation frame is given, which is in good agreement with the experiment data.

Key words: ength of spring, rotation
