Embodiment Construction

[0022] (1) Cargo spacecraft cargo storage structure and constraints

[0023] In addition to storing cargo bags, cargo spaceship shelves can also place lockers, drawers and other storage structures, such as figure 1 As shown, the following constraints are established for the cargo placement of the cargo spacecraft:

[0024] 1. The center of gravity of the loading cargo substructure to be placed can only be located in the storage position of the substructure.

[0025] 2. Only the substructure of the same type and specification can be exchanged. For example, a drawer can only be exchanged with a drawer of the same specification, but the quality of the goods stored in the drawer can be different.

[0026] 3. Each cargo loading substructure is in a discrete state without overlapping.

[0027] 4. The distance between the center of gravity and the geometric center is required to be less than 25mm.

[0028] (2) Cargo spaceship cargo layout optimization algorithm

[0029] Cargo loa...

Abstract

A spaceship load placement method, simulating and simulating the mobile spaceship load unit, setting constraints, and pruning various feasible execution plans according to the constraints until a solution that meets the requirements is found. The specific steps include: determining the spaceship when it is empty and The steps of the mass and center of gravity of each structure after filling the load; the steps of putting each structure into the shelf and judging the current center of gravity of the spacecraft and the geometric center of the spacecraft; according to the relationship between the center of gravity of the spacecraft and the geometric center of the spacecraft, adjust the placement position of the secondary structure until it is adjusted successively After approaching and satisfying the specified distance, the adjustment procedure ends. The present invention does not need to traverse all cargo layout modes, and finds the cargo loading mode that meets the requirements at the fastest speed, greatly saving calculation time.

Description

technical field [0001] The invention relates to a spaceship load placement method, in particular to a load placement method designed according to the storage characteristics of a cargo spaceship, and belongs to the intersection field of manned space vehicle structure and cargo loading design. Background technique [0002] Studies have shown that the optimization of the cargo combination of a cargo spacecraft can effectively reduce fuel consumption, which is an important prerequisite for the spacecraft to successfully complete orbit control, attitude adjustment, and docking. Studying the cargo space layout of a cargo spacecraft is of great significance to spacecraft orbit control. [0003] The loading of goods has a strong engineering representation, but it is difficult to find its optimal solution, because this kind of problem belongs to the combinatorial optimization problem, usually there are a large number of executable solutions, this kind of problem has been proved to be...
