Neither method can meet the actual needs. For example, for the design of the protective shape, the method of increasing the thickness of the product shell or selecting anti-deformation materials is usually used to reduce the probability of the product being broken down. This method will increase The overall weight and volume of the product do not meet the requirements of lightweight design for outboard products

Embodiment 1
[0032] Such as figure 1 with 2 As shown, the present invention provides a protective structure for space products, including:
[0033] The arc-shaped protective shell 1 is arranged outside the space product shell 2 , and the arc-shaped protective shell 1 is fixedly connected with the space product shell 2 through a mechanical interface 3 . Specifically, the arc-shaped structure design is adopted here to increase the protection ability of space products against micro-meteoroids and space debris. In this embodiment, the arc-shaped protective structure, that is, the arc-shaped protective shell is processed and designed in the form of parts, and is connected with the space product shell through a mechanical interface, which has the advantages of replaceability and secondary protection. Such as figure 1 As shown, F is the collision force, T is the reaction force, and F1 is the resultant force of the collision force and the reaction force. When the micrometeorite or space debris ...
Embodiment 2
[0042] Such as image 3 As shown, the present invention also provides a method, comprising:
[0043] Step S1, setting an arc-shaped protective shell on the outside of the shell of the space product; preferably, a reinforcing rib is provided on the side of the arc-shaped protective shell close to the shell of the space product;
[0044] Step S2, fixedly connecting the arc-shaped protective shell with the shell of the space product through a mechanical interface;
[0045] Step S3, disposing important components at the center of the space formed by the shell of the space product;
[0046] Step S4, arranging non-important parts in the space formed by the shell of the space product around important components;
[0047] Step S5, setting reinforcing ribs between the non-important parts and important components. Preferably, the reinforcing rib is a flat reinforcing rib.
[0048] Preferably, in step S1, the equivalent thickness of the arc-shaped protective shell is determined by th...

Abstract
The invention provides a protecting structure and a setting method of a space product. The protecting structure comprises an arc protecting outer shell which is arranged on the outer portion of an outer shell of the space product. The arc protecting outer shell is fixedly connected with the outer shell of the space product through a mechanical connector. An important element is arranged at the center position in a space formed by the outer shell of the space product. An unimportant part is arranged on the periphery of the important element. A reinforcing rib is connected between the unimportant part and the important element. Damage of different types and different degrees of the space product caused by collision of micrometeors and space debris can be lowered to the maximum degree, the space product is effectively protected during operation, and the reliability of the space product during operation on a track is guaranteed.
Description
technical field [0001] The present invention relates to the technical field of the outer shape protection structure of space products, in particular to the protection structure of space extravehicular products. Background technique [0002] In recent years, international space exploration activities have become more and more frequent, and the number of space debris and micrometeorites produced by human spaceflight activities is becoming one of the main factors that threaten the normal use of orbiting spacecraft. Due to their high kinetic energy, space debris and micrometeorites can break down the shell of the product when they collide with the extravehicular product, resulting in the destruction of important internal components of the product and making the product invalid; even a single micrometeorite can damage the product. The plasma flow generated by the impact of the impact can also damage the electronic devices in the product. In order to ensure the safe and reliable ...
