Electromechanical coupling model-based space net-shaped antenna power load analysis method

Abstract

The invention discloses an electromechanical coupling model-based space net-shaped antenna power load analysis method. The method specifically comprises the steps of (1) inputting antenna geometrical parameter, material parameters and electrical parameters; (2) establishing an antenna structure finite element model; (3) performing antenna structure modal analysis; (4) outputting a modal matrix; (5) applying power load; (6) calculating modal coordinates; (7) calculating reflective surface node displacement; (8) calculating surface patch phase error; (9) calculating an antenna far-zone electric field by adopting an electromechanical coupling model; (10) determining whether electrical performance satisfies requirement or not; and (11) outputting an antenna structure design scheme, or (12) updating the antenna parameters and continuing to perform the step (1). By virtue of the electromechanical coupling model-based space net-shaped antenna power load analysis, the space net-shaped antenna electrical performance analysis and electromechanical integration optimization design can be guided under the effect of vibration load.

AI Technical Summary

Benefits of technology

This patented technology helps predict how well an electronic device will perform its function properly when placed near or inside space (a planet). It does this by analyzing the properties of materials that make up the physical structures around it and adjust their dimensions accordingly. By doing these calculations, engineers are able to optimize the placement of electronics within them without adding extra weight or making changes over time. Overall, this innovation improves the efficiency and effectiveness of wireless communication systems.

Problems solved by technology

Inspired by these technical features described earlier (the patents) there was developed a new way to study how different types of stress or strain may change the shape of an interference pattern antenna's surface during use at high altitudes without causing any significant effects on its function over long periods of time. However, current methods have limitations when applied to studying the effectiveness of dynamically loaded materials like metal meshes on satellite communication systems.
