Therefore, this paper proposes the fluid solid coupling method, and then carries out joint simulation for the dynamic performance of air spring combined with the software SIMPACK and Matlab Simulik, which can overcome the nonlinear stiffness and hysteresis characteristics.
Fluid solid coupling mechanics is a branch of mechanics that is produced by the intersection of fluid mechanics and solid mechanics.
The fluid solid coupling problem can be defined by its coupling equation, the domains of which both include the fluid domain and the solid domain.
The basic idea of fluid solid coupling is to use the ABAQUS finite element software and STAR-CCM+fluid analysis software to carry out co-simulation, that is, to establish the solid part of the ABAQUS software, its modeling process is similar to the air spring stiffness modeling method, but the density of structural material need to be added additionally.
If both shafts are assembled in self-aligning bearings then zero misalignment can be achieved, allowing the use of a solid coupling
which simply supports the shaft in perfect alignment.

The quasi steady state theory is adopted to describe the fluid solid coupling process of vortex-induced vibration based on the finite volume method coupled Gauss equation.
The above mathematical expressions include the solving process of fluid solid coupling and electromechanical coupling.
Thus, the fluid solid coupling problem can be solved by interactive computing.
