Problems solved by technology

Therefore, the design and performance of the tether take-up mechanism play a very important role in whether the space tether system can successfully complete the task. For example, in the above-mentioned TSS-1 on-orbit test, the technical failure of the tether release mechanism made the tether Broken due to excessive tension, resulting in mission failure

Abstract

The invention discloses a large-tension long tether winding-unwinding device used for a tethered system combination. A tether posture inlet angle measuring part, a tether guiding part, a tension pre-tightening part, a tether length measuring part, a tension measuring part, a tether arrangement part and a tether winding part are sequentially mounted in a shell in the length direction of the shell. The large-tension long tether winding-unwinding device has the functions that the tether posture inlet angle is measurable, and the lengths and tension of tethers are measurable and controllable. The large-tension long tether winding-unwinding device is provided with the tether arrangement part, so that when multiple tethers are collected on a winding drum, the tethers can be uniformly arranged on the winding drum, and accordingly the toppling-down phenomenon caused by mutual extrusion of the tethers is avoided; and in order to guarantee both tension precision and the measuring range, a large-measuring-range tension sensor and a small-measuring-range tension sensor are connected in series to measure the tension of the tethers, so that the tether winding-unwinding device has large tension (the maximum controllable and measurable tension is 200 N) and is suitable for the long tethers (the maximum tether winding length is 200 m) and high in precision.

Description

technical field [0001] The invention relates to a space tether control device, in particular to a large tension long tether retracting device for a space tether assembly. Background technique [0002] Space tether systems generally use flexible tethers that are easy to coil. During the on-orbit operation of the system, it is generally necessary to control the length or tension of the tether through the tether coiling mechanism connected to the end of the tether. Therefore, the design and performance of the tether take-up mechanism play a very important role in whether the space tether system can successfully complete the task. For example, in the above-mentioned TSS-1 on-orbit test, the technical failure of the tether release mechanism made the tether It broke due to excessive tension, resulting in the failure of the mission. For the space tether system, the tether control mechanism is the actuator that controls the length, velocity and tension of the tether, and must be co...
