Proposed is an anti-vibration mount using combination of multiple springs in which a main spring is provided between an upper frame and a lower frame to reduce vibration, and an auxiliary spring is provided at each of the side portions of the upper frame such that the direction and magnitude of a force applied by the auxiliary spring change according to the compressed degree of the main spring, so the effect of an air spring is realized only with the combination of the main and auxiliary springs which are coil springs. The anti-vibration mount includes: the upper frame allowing an object to be installed thereon; the lower frame provided under the upper frame by being spaced apart therefrom; the main spring provided between the upper frame and the lower frame; and the auxiliary spring elastically supporting each of opposite sides of the upper frame and the lower frame.

A vibration damping and sound insulating device installed on an installation object, includes: vibrators disposed at a prescribed spacing. Each of the vibrators includes: a cylindrical tubular member on the installation object; an elastic body supported by the cylindrical tubular member such that the elastic body traverses a hollow portion of the cylindrical tubular member along a direction orthogonal to an axis of the cylindrical tubular member; and a weight on the elastic body.

A variable acceleration curved surface spiral gear transmission mechanism for accelerated oscillator damper damping systems is disclosed. Through the orthogonal orbit planetary gear set moving along the parallel circular arc line guide rail, the concave surface spiral gear and the convex surface spiral gear are meshed at different radii, so as to realize the continuous changing of the speed ratio and changing of the acceleration of the additional mass block. The spiral curve limit guide groove is set on the surface of concave surface spiral gear and convex surface spiral gear, and the changing rate of speed changing ratio is adjusted by designing different spiral curves, and then the acceleration changing rate of additional mass block is controlled.

A vibration isolator, system, and method for minimizing propagation of vibrations between structures are configured to decouple axial and lateral structural modes. The vibration isolator includes an axial flexural support that provides axial compliance relative to a central axis and a lateral elastomeric support that provides lateral compliance relative to the central axis. The axial flexural support and the lateral elastomeric support provide stiffness about the central axis. The vibration isolator includes a first mount coupled to a first external structure and a second mount coupled to a second external structure. The axial flexural support is coupled to the first mount and the lateral elastomeric support is coupled to the second mount and the axial flexural support. Using an axial flexural support and a lateral elastomeric support enables tuning of the structural modes in one axis while minimizing the effects to the structural modes in the orthogonal axes.
