| Summary: |
|
- High-precision actuation and mechanical sensing are critical functions in aerospace equipment, serving as the foundational components for achieving high-precision control of such systems. For instance, during the link establishment process for inter-satellite laser communication, in-orbit angle adjustment with "threading a needle from ten thousand miles away" level precision, real-time capability, and high speed is required. This challenge is underpinned by scientific issues such as the hysteresis and creep nonlinearity of piezoelectric ceramics. Another example is the need for ultra-low frequency micro-vibration sensing and measurement in large space structures to enable vibration suppression, where existing sensor devices face shortcomings like low sensitivity. There is an urgent need to develop new methods and novel mechanisms for high-precision actuation and mechanical quantity sensing, followed by applied research based on these advancements.
This session will focus on the above issues, aiming to establish a communication platform for innovative achievements among university researchers and technical R&D/engineering personnel from aerospace enterprises. It seeks to help participants clarify industry demands and academic frontier trends, break down barriers between research and application, promote the transformation of technological achievements and interdisciplinary collaboration, and thereby foster academic innovation and high-quality synergistic development between industry and academia in the field of high-precision actuation and mechanical quantity sensing for aerospace applications.
