| Abstract: | The bearing is expressed with the constrain matrix, and the high speed painting automizor system is described with elastic coupling beam, then adopted modal synthesis method to build the dynamic model.Considering the eccentricity of painting cup and automizor tray at the end of rotor to build the model of force, and analyzed the response of the end of rotor. Then, the natural frequency, modal and other dynamic characters of the coupling system are studied, the law of bearing to coupling frequency and amplitude of rotor end is also found.Then, the foundation of absorber vibration is established and maintained. |
