The prototype is suitable for aviation The multi-parameter matching test of the prototype shows that the coupled shock absorber has strong nonlinear dynamic characteristics. On the basis of the above analysis, a complex modeling method is combined with the theoretical analysis to establish the nonlinear dynamic model of the prototype. The modeling method is directly introduced The structure parameters of the vibration isolator are used to establish the theoretical basis for the direct design of specific devices. The research shows that the coupling shock absorber has superior performance and good design controllability. The modeling method can be applied to other vibration-damping device research and design
