一种微低重力系统绳偏角实时动态测量装置及方法
By combining photoelectric encoders and inertial measurement units, the rope deflection angle is measured in real time, which solves the problem that the longitudinal motion constant force system is difficult to achieve large load unloading. This enables reliability assessment in zero-gravity vertical flipping and unfolding tests of large, heavy-duty products.

AI Technical Summary
In existing technologies, constant force systems with longitudinal motion are difficult to unload large loads, and the absolute deflection angle of the rope cannot be directly measured by existing measuring tools such as inclinometers, resulting in low engineering practicality. Visual measurement technology also suffers from problems such as data processing delays and high costs.
By combining photoelectric encoders and inertial measurement units, the angular changes of rotating parts and the included angle of the suspension rope are measured in real time to dynamically measure the rope deflection angle. Combined with the inertial measurement unit and photoelectric encoder, the suspension rope is kept in a plumb state at all times. The power unit and gravity unloading components are used to realize the zero-gravity vertical flipping and unfolding of large, heavy-duty products.
It enables reliability assessment of large, heavy-duty products in zero-gravity vertical flipping and unfolding tests. The suspension rope is always kept in a plumb bob state, which improves measurement accuracy and engineering practicality. It is suitable for zero-gravity vertical flipping and unfolding tests of large, heavy-duty products.
