英文摘要：

No-avoidance-typed stereo garage is put as the research object in this paper. First of all, the nonlinear dy- namic model of no-avoidance-typed stereo garage has been constructed by the finite-element method for its lifting operation process. Then the nonlinear vibration characteristics of no-avoidance-typed stereo garage have been analyzed, and the internal relations that are between the no-avoidance-typed stereo garage＇s dynamic characteristics and its structural parameters, material parameters, motion parameters have been proven. Finally the dynamie characteristics of no-avoidance-typed stereo garage have been analyzed under the self-excited force through an example and the useful conclusions have been got.
