| Objective To speed up the design process of rubber absorber. Methods The characteristics of rubber material and the Mooney-Rivllin rubber constitutive model were analyzed. The characteristics of rubber absorber and the basic theory of vibration isolation design were introduced. Mechanical properties of rubber materials were simulated with Mooney-Rivllin model. By introducing the finite element optimization design technology, the stiffness characteristics of absorber was guaranteed in the early design stage. Results In the vibration damping design of a certain equipment, parameters of Mooney-Rivllin model for rubber materials were obtained with an uniaxial tension and compression curve. With the design parameters of the vibration damper part structure and the three direction stiffness of the absorber as the design target, the vibration isolation system (axial frequency 40 Hz, radial frequency 40.9 Hz) with the same three axial stiffness was designed. The test shows that there was small difference between frequency and test values of the vibration reduction system. The axial difference was 2% and the radial difference was 1%. Conclusion By introducing the finite element optimization technology, the design of rubber absorber progress is greatly shortened. |
