Abstract

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-vibration pad is obtained. According to the method, the rubber anti-vibration pad can be modeled to a certain extent, so that a reliable dynamic model is provided for subsequent calculation.

Description

technical field [0001] The present application relates to the technical field of simulation modeling, and in particular, to a modeling method for rubber vibration damping pads. Background technique [0002] In order to improve the mechanical environment of the satellite and reduce the vibration energy transmitted by the structure, elastic rubber vibration damping pads will be used between the adapter and the rocket structure and between the satellite and the adapter. Due to the addition of rubber damping pads, the modeling of the connection parts is more difficult, and higher requirements are put forward for the treatment of local connection parts and the establishment of the dynamic model of the rubber damping pads. If refined modeling is used, the modeling is difficult and requires many correction parameters, which is not suitable for general engineering applications. [0003] Therefore, those skilled in the art are in urgent need of a modeling method for rubber vibration...
