Description

Technical Field

[0002] Rotary axes have extensive and important applications in many fields. They are not only crucial for the design and analysis of mechanical structures in the engineering field, but also in the aerospace field, the design and control of aircraft cannot be separated from the accurate grasp of rotary axes. For satellites in space, attitude control is crucial for their normal operation and mission completion. With its unique properties and wide applications, rotary axes occupy an important position in many fields such as engineering, physics, and materials.

[0003] Missing rotary axis measurement brings a series of problems and challenges. Accurate measurement of rotary axes is crucial to equipment stability, performance optimization, control accuracy and safety. In complex mechanical systems such as aerospace, centrifuges, crankshafts, etc., if the rotary axis is not accurately measured or determined, the actual attitude information of the object cannot be accurately obtained. This leads to problems such as heading deviation and control correction lag. The rotating parts of the system may produce significant vibration and imbalance. This leads to increased equipment loss and vibration. In many industrial applications (such as large blowers, generators, etc.), missing or inaccurate measurements will lead to imbalance of rotating parts and stress overload of equipment structures.

[0004] In modern manufacturing, the requirements for product precision are getting higher and higher. Especially in the fields of aerospace, precision instruments, electronics, etc., small errors may lead to serious consequences. The composite rotary axis ultra-precision measuring instrument can provide extremely high measurement accuracy, accurately detect various parameters of the rotary axis, and provide reliable data support for high-precision manufacturing. For example, in the manufacture of aircraft engines, the accuracy of the rotary axis directly affects the performance and reliability of the engine. By improving the accuracy of the measuring instrument through technical research, high-quality production of the engine can be ensured.
