Problems solved by technology

[0008] The purpose of the present invention is to solve the problem that the existing elastic vibration damping method is difficult to apply to various load conditions, especially the existing elastic vibration damping elements cannot meet the requirements of improving the axial stiffness of the elastic composite element and reducing the radial and deflection stiffness. A new method of improving the axial stiffness of the elastic composite element and reducing the radial and deflection stiffness is proposed. This method of increasing the axial stiffness of the elastic composite element and reducing the radial and deflection stiffness can greatly improve the comprehensive vibration reduction of the motor suspension Performance, improve the axial stiffness of the elastic composite element and reduce the radial and deflection stiffness, effectively meet the elastic vibration reduction requirements of the motor suspension of the high-speed train system

Embodiment 1

[0035] It can be seen from the accompanying drawings that the present invention relates to a method for improving the axial stiffness of an elastic composite element and reducing the radial and deflection stiffness. The axial precompression and suspension bearing of the multi-free surface elastic element 1 improve the axial stiffness of the elastic composite element. To the stiffness and reduce the radial and deflection stiffness; the multi-free surface elastic element 1 is a composite of the elastic body 2 and the metal part 3, and the elastic body 2 has 3 and more than 3 free surfaces after the composite, so that the elastic body is in the The stress in each direction is greatly reduced, improving the anti-fatigue life; the axial precompression is that the elastic body 2 is always in the axial precompression state during the working process, and the axial stiffness is greatly improved; the suspension type Bearing means that during the working process of the elastic element, a...

Embodiment 2

[0046] The principle of the second embodiment is the same as that of the first embodiment, only slightly different in structure. A method for improving the axial stiffness of an elastic composite element and reducing the radial and deflection stiffness, through axial precompression and suspension bearing of a multi-free surface elastic body to improve the axial stiffness of the elastic composite element and reduce the radial and deflection stiffness; The multi-free surface elastic body is that when the elastic element is combined with the metal part, the elastic body has more than 3 free surfaces after the composite, so that the stress of the elastic body in all directions is greatly reduced, and the fatigue life is improved; the described Axial precompression means that the elastic body is always in the axial precompressed state during the working process, which greatly improves the axial stiffness; the suspension type load means that at least one metal body is suspended durin...

Abstract

A method for improving the axial stiffness of the elastic composite element and reducing the radial and deflection stiffness, through the axial precompression and suspension bearing of the multi-free surface elastic element to improve the axial stiffness of the elastic composite element and reduce the radial and deflection stiffness; the described The multi-free surface elastic element is a composite part of an elastic body and a metal part. After the composite, the elastic body has 3 or more free surfaces, which greatly reduces the stress of the elastic body in all directions and improves the anti-fatigue life; the said Axial pre-compression means that the elastic body is always in the axial pre-compression state during the working process, which greatly improves the axial stiffness; The body is in a suspended state, so that the metal body is not loaded, so that the elastic body there is completely in a shear state and does not provide radial stiffness, thereby increasing the axial stiffness of the elastic composite element and reducing the radial and deflection stiffness.
