Abstract: Firstly, the method of characteristic root was used to  analyze the  stability  of delayed oscillator with delaydependent parameters, and  a criterion for stability switches was given. Secondly, the  stability and periodicity of bifurcating periodic solutions were analyzed by using the center manifold and  the normal form theory.

Key words: inertial term, delay, stability switch, Hopf bifurcation
