Vibrating table for centrifugal machine

Abstract

The invention relates to a vibrating table for a centrifugal machine, which comprises a stand. A vibrating table moving coil for generating vibrations and a test platform for a carrier belt to test workpieces are arranged on the stand, and the left end of the test platform is linked with the vibrating table moving coil through a platform push rod; the right end of the test platform is connected with a deviation correcting mechanism for preventing the vibrating table moving coil from excessively deviating on axial direction through a deviation correcting push rod; an aluminum frame of the vibrating table moving coil is provided with supporting mechanisms for preventing the moving coil from twisting or circumferentially rotating, convex edges are uniformly distributed on the aluminum frame, and one supporting mechanism is arranged between any two adjacent convex edges; each supporting mechanism comprises an axial spring installed on the convex edges along the axial direction of the moving coil and a radial spring installed along the radial direction of the moving coil to connect the axial spring and the aluminum frame; and the right end and the left end of the aluminum frame are both provided with radial springs. The invention has the advantages of correcting the deviation of a moving part in centrifugation environment and being directly used for the centrifugal machine.

Description

technical field [0001] The invention relates to a vibrating table, in particular to a vibrating table which can be directly applied in a centrifugal environment. technical background [0002] The rapid development of my country's aerospace industry puts forward higher and higher requirements for the reliability of aerospace devices. The life of various components inside the space device is directly related to the reliability of the space device. It is of great theoretical and practical significance to conduct reliability accelerated environmental tests on these components. However, the single-parameter environmental test cannot fully simulate the working environment of aerospace device components. In order to improve the accuracy of the environmental test, it is necessary to build a multi-parameter compound environmental accelerated test system, and to study the compound environmental test and the coupling between various environmental factors. [0003] The combination of...
