Non-linear elastic auxiliary vibrating device and vibration swinging bench

Abstract

The invention discloses a non-linear elastic auxiliary vibrating device and a vibration swinging bench and aims to solves the problems that the design, manufacturing and usage cost of the vibration swinging bench caused by large power consumption is greatly increased in the research of the vibration swinging bench, and the vibration swinging bench meeting the usage requirements is not available. The vibration swinging bench comprises a support platform (1), four non-linear elastic auxiliary vibrating devices (2), four support seats (3) and three vibration exciters (4). The three vibration exciters (4) are installed between the support platform (1) and a base (5) through spherical hinges. The four non-linear elastic auxiliary vibrating devices (2) are symmetrically arranged on the periphery of the support platform (1). The four non-linear elastic auxiliary vibrating devices (2) are respectively and fixedly connected with one side of the support platform (1) through one tongue-shaped plate. The four non-linear elastic auxiliary vibrating devices (2) are installed on the four support seats (3). The bottom end of the support seats (3) are fixedly connected with the base (5).

Description

technical field [0001] The invention relates to a device belonging to the field of vibration environment test. More specifically, the present invention relates to a nonlinear elastic auxiliary vibration device and a vibration rocking table including the vibration device. Background technique [0002] Vibration rocking table is a device that can reproduce the vibration environment of the test piece, and is used to study the reliability and stability of the test piece under different vibration environments. When the mass of the test piece is large and the vibration displacement, velocity and acceleration amplitude are required to be high, and the specific vibration test conditions are met, the input power required by the vibration rocking table will increase significantly. Restricted by the cost of design, manufacture and use, the scope of application of the existing vibratory rocking table is limited. [0003] In order to save energy, improve efficiency, and expand the scop...
