| Zusammenfassung: | The embodiment of the invention provides a modeling method for a rubber anti-vibration pad, and the method comprises the steps: carrying out the modeling of the joints of the rubber anti-vibration pad and upper and lower end structures through modeling software by using RBE2 rigid units, and carrying out the modeling of the rubber anti-vibration pad between the RBE2 rigid units by using a BUSH unit, and obtaining an initial model of the rubber anti-vibration pad; respectively setting a rigidity initial value and a damping ratio initial value of the initial model; acquiring actual frequency characteristics and actual damping ratio characteristics of the rubber anti-vibration pad; and according to the actual frequency characteristics of the rubber anti-vibration pad and the actual damping ratio characteristics of the rubber anti-vibration pad, the rigidity initial value and the damping ratio initial value of each degree of freedom of the initial model are optimized, and a target model of the rubber anti-vibrati |
