Abstract

The invention provides a pull tab force bearing measuring device and method. The device comprises a pull tab to be tested, an aerostat bag body and a plane blowing structure, wherein the pull tab to be tested is fixed on the aerostat bag body, the aerostat bag body is installed on the plane blowing structure, and the aerostat bag body and the plane blowing structure form an inflatable closed space. The method includes the steps of fixing the pull tab to be tested on the aerostat bag body, installing the aerostat bag body on the plane blowing structure, inflating the inflatable closed space formed by the aerostat bag body and the plane blowing structure, allowing the pressure in the closed space to be the working pressure of the pull tab to be tested during actual use, and measuring the force-bearing value of the pull tab to be tested when the pull tab to be tested is separated from the aerostat bag body. The air pressure load in a closed space formed by the aerostat bag body and the plane blowing structure of an aerostat when the pull tab to be tested is in actual use is simulated, and the force-bearing value of the pull tab to be tested in the aerostat in actual use can be truly and accurately measured.

Description

technical field [0001] The invention relates to the field of mechanical fasteners, in particular to a device and method for measuring the force of a pull tab. Background technique [0002] Aerostats are aircraft that use lighter-than-air gases (hydrogen, helium, hot gas, etc.) to provide lift. They are widely used in military and civilian fields due to their advantages such as long time in the air, energy saving, environmental protection, and economy. There are mainly two types of aerostats: tethered balloons and airships. Tethered balloons generally have no power system and are connected to ground equipment or stations by tethered cables; airships are powered and can fly autonomously under remote or automatic control. [0003] Whether it is a tethered balloon or an airship, the pull tab is processed on the aerostat capsule and is an indispensable part. Pull tabs can be divided into I-shaped pull tabs, V-shaped pull tabs, and double V-shaped pull tabs according to their sha...
