This paper presents an analysis of nonlinear oscillations as responses of saturating servomechanisms subjected to periodic inputs.<BR>Conditions that make a system output oscillate with a subharmonic of the input frequency have been obtained.The possibility of the occurrence of subharmonic oscillations or frequency divisions can be estimated from the maximum value of theoutput-input amplitude ratio for a given input amplitude.<BR>The analytic solution for finding the maximum value of the output-input amplitude ratio of a saturating second order servomechanism as well as the analytic solution for finding the frequ ency response of such a system have been obtained.
