AI Technical Summary

Benefits of technology

This new design uses an electronic circuit board (PCB) technique called Printed Circuit Boards(PCBA). It achieves this through adding special components like resistors and capacitors on both sides of the PCBA substrate. By doing these things we create a more stable system than previous designs due to its ability to achieve similar levels of rigidity at different angles along each direction compared to traditional methods such as steel balls or rubber bands. Additionally, it allows us to adjust the stifferess based on how much force they apply during operation, resulting in improved performance over time. Overall, our innovations improve the efficiency and effectiveness of space systems' mounting techniques.

Problems solved by technology

This patented problem addressed in this patents relates to improving the stability or immune response time required by precise instrument systems used during mission operations at extreme temperatures (EoC). Traditional methods have limitations with regard to achieving both small and large amplitude movements caused by temperature changes over their lifespan. Therefore there needs an active system that provides effective vibrational isolations even after being exposed to extremely cold conditions without requiring expensive equipment like sensors or electronic components.

Abstract

The invention discloses a space six-degree-of-freedom non-contact vibration isolation platform for aerospace, comprising a base, a working platform, and first to fourth electromagnetic vibration isolators arranged between the base and the working platform; each The vibration isolators can achieve vibration isolation in the x and y directions in the plane. The four vibration isolators are evenly distributed on the four sides of the base. The platform has low natural frequencies in the six degrees of freedom, which can effectively suppress the vibration of the six degrees of freedom Low frequency micro vibration. The present invention is applicable to the vibration isolation of equipment in the field of aerospace precision instruments. When the platform base is disturbed and vibrations are generated in six degrees of freedom, these vibrations can only be transmitted to the precision load through the vibration isolation platform, while the platform Its own stiffness is extremely low, which greatly reduces the disturbance of precision loads.
