Lithium battery vibration test fixture for launch vehicles

Abstract

The invention provides a launch vehicle-used lithium battery vibration test fixing device, which comprises a vibration bottom plate, positioning assemblies, depression bars, pulling rods and ties, wherein the vibration bottom plate is provided with countersunk mounting holes and fastening threaded holes; each positioning assembly comprises a positioning plate, a backing plate and a fixed steel strip assembly; one end of the fixed steel strip assembly is fixedly connected with one side, close to a horizontal plate, of a vertical plate through the backing plate, and the other end is movably connected with a first tightening piece; two ends of each tie are movably connected with second tightening pieces; and two ends of each pulling rod are provided with thread matched with the threaded through holes in the first tightening piece and the second tightening piece. The problem of mounting and fixing for a launch vehicle-used lithium battery vibration process with no mounting leg support or no mounting and fixing hole position can be solved, being close to the real state of the launch vehicle-used lithium battery in a flight stage is realized, the mounting is convenient, the structure strength is high, the fixing is reliable, and the launch vehicle lithium battery can be effectively fixed for the vibration test.

Description

technical field [0001] The invention relates to the field of vibration tests, in particular to a vibration test fixture for lithium batteries used in launch vehicles. Background technique [0002] In order to test the ability of the lithium battery for the launch vehicle to withstand mechanical vibration during the flight of the rocket, it is necessary to fix the lithium battery for the launch vehicle on a vibration table for vibration testing. The vibration test process should be able to fully simulate the installation and fixing state of the lithium battery for the launch vehicle . [0003] CN103323196A "Vibration Tooling for Square Batteries" is aimed at the vibration of square batteries, and its test efficiency is high, but its fixed battery weight is limited, and the installation method cannot simulate the real environment on the arrow; Bundled vibration tooling, which is suitable for vibration testing of arc-like products, and the lithium battery of the launch vehicle...
