Hybrid fitting method for dynamic responses of mechanical systems
Frontiers in Mechanical EngineeringFor linear system, vibration response can be obtained by working load and vibration transfer function. However, for nonlinear systems, the vibration transfer function is variable, so the error of the existing methods is obvious.
