摘要：
Spur gear servomechanism is widely used in photoelectric stabilization platform and other weapon system, its resonance characteristic directly determines the bandwidth, gain and stability of the whole subsystem. Taking Spur gear servo mechanisms as research aim, three degrees of freedom vibration differential equation of gear mesh is theorized, and the resonance equation of the servo mechanism is obtained through Laplace transform, and then the vibration characteristic of stabilization platform is analyzed by numerical analysis. A new kind of resonance frequency analysis method is proposed based on virtual test technology. The digital simulation model of mechanism is created in MATLAB, and then the virtually frequency sweep method is used to excite the resonance characteristic of servo mechanism. The resonance frequency was obtained by analysis of curve of servo mechanism in time domain and frequency domain. Result of numerical analysis and virtual test show that the inertia moment of high speed axes and the mesh stiffness of gear are key assembly and sensitive parameter of the Spur gear servomechanism.
