Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to a connection device for satellite loads and a honeycomb panel using the connection device. Background technique [0002] Honeycomb panel is one of the commonly used structural components in the aerospace field, which has the advantages of high strength-to-mass ratio, excellent stiffness-to-mass ratio, and simple structure. Honeycomb panels are usually glued or screwed to mount stand-alone equipment or payloads. Since the honeycomb panel is usually composed of a thin panel and a hole-shaped soft sandwich, it is not possible to directly process through holes or threaded holes on the honeycomb panel to install stand-alone equipment, but to install it by pre-embedding or post-embedding metal embedded parts in the honeycomb panel. Stand-alone equipment, transferring concentrated force loads. In general, the connection design of the honeycomb panel will pre-embed or post-bury a co...

Problems solved by technology

All connection points in this design method are relatively independent. Under the action of dynamic load, the relative stiffness of each connection is different, which will cause a relatively large dynamic displacement difference at each connection point. For the dynamic displacement difference of ordinary load It has no effect, but for loads with high precision requirements, such as optical cameras, such a dynamic displacement difference will cause torsional deformation of the main part of the optical camera, thereby affecting the imaging quality of the optical camera

[0004] In order to solve the requirements of high precision loads on connection stiffness, the design of embedded parts of honeycomb panels must have high rigidity, so as to avoid large dynamic displacement differences caused by high precision loads under dynamic loads , thereby affecting the working quality of loads with high precision requirements
