Problems solved by technology

At present, there are three types of vibration damping devices for the lithium battery of the launch vehicle. The first type is to spread damping materials on the mounting surface of the lithium battery of the launch vehicle, such as aviation rubber plates and aviation foam plates. This vibration damping method can realize small vibrations. It is difficult to apply to the situation of strong vibration and strong impact; the second method is to install a shock absorber to achieve the vibration reduction effect. This vibration reduction method can select a suitable shock absorber according to the intensity of the vibration, but it is difficult to achieve vibration isolation and poor maintainability. It can only be replaced; the third type of lithium battery is surrounded by cushioning materials, which takes up a lot of space and costs a lot

Embodiment Construction

[0014] The present invention will be further explained and illustrated below in conjunction with the accompanying drawings and specific embodiments.

[0015] figure 1 It is the general assembly drawing of the system of the self-adaptive flexible damping device for the lithium battery of the launch vehicle of the present invention. Because the lithium battery used in the launch vehicle is subjected to severe vibration and shock during flight, a system of adaptive flexible damping device is designed to relieve the vibration and shock during flight. Such as figure 1 As shown, the adaptive flexible damping device for the lithium battery of the launch vehicle of the present invention comprises a lithium battery shell of the launch vehicle 1, an adaptive load release mechanism 2, a flexible grid damping mechanism 3, a vibration isolation support seat 4 and a bolt 5; The cell part of the lithium battery of the launch vehicle is packaged in the lithium battery shell 1 of the launch ...

Abstract

The invention provides a self-adaptive flexible damping device for a carrier rocket lithium battery, which is characterized by comprising a carrier rocket lithium battery shell (1), a self-adaptive load release mechanism (2), a flexible grid vibration damping mechanism (3), a vibration isolation support seat (4) and a bolt (5); the self-adaptive load release mechanisms (2) are mounted on two opposite sides of the carrier rocket lithium battery shell (1) in a welding manner; the flexible grid vibration buffering mechanisms (3) are installed on the other two opposite sides of the carrier rocket lithium battery shell (1) in a welded mode; and the vibration isolation supporting seat (4) is fixed on the mounting feet of the carrier rocket lithium battery shell (1) and a rocket platform through bolts (5). Compared with the prior art, the device has the advantages that for vibration impact in the launch process of the launch vehicle lithium battery, the purposes of vibration isolation, vibration absorption and rapid vibration load release are achieved, and the adjustable and controllable effects are achieved according to launch vibration environments of different types of launch vehicles.

Description

technical field [0001] The invention relates to a flexible damping device in a launch vehicle, in particular to an adaptive flexible damping device for a lithium battery of a launch vehicle. Background technique [0002] The launch vehicle will generate high-frequency vibration during launch, which will easily affect the reliability of lithium batteries, and may cause safety problems, affecting the success or failure of the launch. Therefore, it is the key to the stable use of lithium batteries to take reasonable anti-vibration measures to reduce the impact of lithium batteries on emission vibration. At present, there are three types of vibration damping devices for the lithium battery of the launch vehicle. The first type is to spread damping materials on the mounting surface of the lithium battery of the launch vehicle, such as aviation rubber plates and aviation foam plates. This vibration damping method can realize small vibrations. It is difficult to apply to the situa...
