Parametric vibration is one of the main reasons for the failures of radial gates. This paper presents three calculation models of the parametric vibration of radial gates which reflect the mechanical properties and geometric features of the gates. Two most commonly used analysis methods, i.e., Bolotin’s method and the finite element method, were described to determine the boundaries of regions of the dynamic instability of radial gates. A numerical example concerning finite element method was also demonstrated.
