Abstract

The invention relates to a lightweight design method of a space-based large-aperture reflection mirror, which belongs to the technical field of a lightweight design of a space remote sensing large-aperture reflection mirror, and aims at solving the technical problems in the prior art that a traditional reflection mirror lightweight design method has the defects of low design efficiency, long design period, and uneasiness of obtaining an optimal mirror body structure. The lightweight design method of the space-based large-aperture reflection mirror, provided by the invention, adopts a comprehensive optimization design method combining a traditional experience design, a topological optimization design and a size parameter optimization design to carry out a structural design of a mirror body; a lot of repeated iteration work is finished by a computer, so that a lot of manpower is saved and the design efficiency is high; and a design process is rapid in convergence and the mirror body structure with optimal properties can be obtained rapidly.

Description

technical field [0001] The invention belongs to the technical field of lightweight design of space remote sensing large-diameter reflectors, and in particular relates to a lightweight design method for space-based large-diameter reflectors. Background technique [0002] Space remote sensors are used to conduct general surveys and detailed surveys of earth and space resources, and their applications in fields such as earth observation and space exploration have important scientific and economic significance. The optical elements in the remote sensor, especially the large-aperture mirror, are the most important components in the entire optical system, and its surface shape accuracy is directly related to the imaging quality of the entire remote sensor. [0003] With the continuous improvement of the resolution and detection sensitivity of space remote sensors, the aperture of the reflector is getting larger and larger. Reflectors are the key components of space optical remote...
