n order to investigate hanger’s characters of auto-adaptation vibration isolation, it was used the promoted Stribeck friction model in which the effects of both pressure and relative velocity to the glide friction force influence were concerned. According to the improvement of the friction model frame structure design, Runge-Kutta numerical method was used to calculate the hanger free response, forced response and the shock response. Results indicate that the excitation of the hanger in cosine, both for high amplitude (30 mm) low frequency [ω=0.1 ωn→ωn]and low amplitude (5 mm) [ω=1.4 ωn→6 ωn] hase good isolation. Also, it indicates that the system has a certain amount of resistance to shock.
