Damping pipe support type damping adapter

Abstract

The invention discloses a satellite-launcher connecting device which can effectively restrain structure vibration and improve the satellite mechanical environment at a launcher active flight section and particularly relates to a damping pipe support type damping adapter. The damping pipe support type damping adapter mainly comprises an upper end frame, eight upper end frame connectors, 16 shearing type damping pipes and eight lower end connectors. The eight upper end frame connectors and the eight lower end connectors are distributed in the periphery direction symmetrically. Each connector is connected with two damping pipes. Each damping pipe is connected with an upper connector and a lower connector in a crossing mode. A whole adapter structure with damping performance between a satellite and a launcher is formed, good damping and vibration isolation performance is achieved, the rigid index requirement which is needed for the adapter structure is met, and the requirement that structure weight is not increased is met.

Description

technical field [0001] The invention relates to an adapter connection product between satellites and rockets. The product is integrated, has good vibration damping performance, and can improve the mechanical environment of satellite payloads. Background technique [0002] The dynamic environment generated by the active flight phase of the launch vehicle is the main design basis for the satellite payload. According to a study by NASA in the United States, 45% of the damage and failures caused by the first launch of satellites are caused by the harsh vibration environment of the active flight stage of the launch vehicle. In the development process of domestic satellites, the development period of the satellite payload structure is sometimes extended because it cannot pass the ground vibration test, or the structural design is relatively cumbersome in order to pass the ground vibration test, which greatly reduces the payload ratio of the satellite. How to improve the mechanica...

Problems solved by technology

The method of vibration isolation through the combination of vibration isolation units has great limitations: the processing accuracy of a single vibration isolation unit is high, the assembly process is complicated, and the flatness and parallelism of the upper and lower mounting surfaces composed of multiple vibration isolation units are difficult to guarantee; The uneven force of the damping material limits the damping effect of the damping layer and affects the performance of vibration reduction and vibration isolation
