Embodiment Construction

[0037] Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail:

[0038] This invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. In the drawings, components are exaggerated for clarity.

[0039] According to the non-destructive use requirement of the parafoil group strap, in order to avoid the damage of the sensor to the group strap, the present invention adopts a tension sensor with a non-invasive structure. While not destroying the strength of the lifting band, the measuring principle is not complicated, easy to process and has high measuring accuracy. In order not to affect the parachute opening process, the surface of the sensor is as smooth as possible. During pa...

Abstract

The invention discloses a detachable I-shaped symmetrical parafoil group lifting belt tension sensor device, which comprises a base, first to fourth cantilevers, first to second movable force columns, first to fourth fixed studs, and first to fourth strain gauges, and the base is I-shaped and comprises a fixed force column, a first cantilever beam and a second cantilever beam. According to the invention, a split structure is adopted, so that the sensor can be conveniently mounted and dismounted on the parafoil group lifting belt, and the structure of the group lifting belt cannot be damaged due to the non-intrusive design. The sensor is uniform in stress, the measurement accuracy can be improved, the large-range tension measurement requirement of the group lifting belt is met, meanwhile, the size is smaller, the weight is lighter, the special working requirement of the parafoil is met, and the problem that the tension of the group lifting belt of the parafoil is difficult to measure in real time is solved.

Description

technical field [0001] The invention relates to the technical field of sensor measurement, in particular to a detachable I-shaped symmetrical parafoil group belt tension sensor device. Background technique [0002] The straps are the load-bearing straps used to connect the straps and the canopy in the parafoil system. During the flight of the parafoil, the straps bear a large tension. In addition, the changes in the flying attitude of the parafoil will also be real-time Affects the tension on the lifting straps. Therefore, real-time grasp of the tension of the lifting belt during the parafoil flight is of great significance to the safety and stability of the parafoil flight, and it can also provide important guidance for the research and design of new parafoils. [0003] The current tension measurement of this kind of flat rope includes direct measurement and indirect measurement. The direct measurement method is to cut off the umbrella belt and connect the sensor in series...
