Embodiment Construction

[0034] Below in conjunction with accompanying drawing, the technical scheme of the present invention is described in further detail:

[0035] The present invention may be embodied in many different forms and should not be considered limited to the embodiments described 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.

[0036] like figure 1 As shown, the present invention discloses a non-invasive parafoil control rope tension sensor, comprising first to second elastic beams, first to third fixing components, and first to fourth strain gauges;

[0037]The first elastic beam and the second elastic beam are cuboids with the same structure, and each includes a first end wall, a second end wall, and first to fourth side walls connected end to end, wherein the first side wall is parallel to the fi...

Abstract

The invention discloses a non-invasive parafoil control rope tension sensor, which comprises two elastic beams, three fixing components and four strain gauges; Through groove, two trapezoidal grooves and two force balance grooves; fixing assembly consists of screws, sockets and nuts. The invention adopts a split structure to facilitate the installation and disassembly of the sensor on the parafoil control rope, and the non-invasive design of the side pressure type does not damage the structure of the control rope. The layout of the same elastic beams on both sides can make the force even and improve the measurement accuracy. While meeting the requirements of the measurement range of the control rope tension, the overall size of the sensor is small and light in weight, which is more suitable for the work requirements of the parafoil flight situation, and solves the problem that the tension of the parafoil control rope is difficult to measure in real time.

Description

technical field [0001] The invention relates to the technical field of non-destructive measurement of sensors, in particular to a non-invasive parafoil control rope tension sensor. Background technique [0002] The control rope is the control rope used in the parafoil system to adjust the flight speed and flight direction of the parafoil (two in total, one on the left and one on the left). It is still an important part of parafoil research to explore the influence of the force change of the control rope on the control of the parafoil during the gliding process of the parafoil. Therefore, in the research and design process of the parafoil, it is necessary to monitor and measure the force change of the parachute rope during the flight of the parafoil, to determine the relationship between the control force input and the parafoil response, so as to determine the control force, Control speed and control timing, etc. [0003] There are different types of tension sensors accordi...
