Embodiment Construction

[0017] The Star-Arrow Unlocking and Separating Tape Pretension Tester of the present invention will be described in detail below in conjunction with the accompanying drawings. These descriptions are only illustrative and are not intended to limit the protection scope of the present invention.

[0018] see figure 1 , figure 1 The structural diagram of the Star-Arrow unlocking and separation tape pre-tightening force evaluation instrument of the present invention is given, wherein the pre-tension force evaluation instrument of the present invention includes a power supply module, which provides power supply, The strain gauge 1 and the temperature compensation sheet 2 pasted on the front and back of the tape measure the strain generated by the strain gauge caused by the change of the ambient temperature, and the multi-channel selection board 3 realizes the unlocking and separation of the star and arrow. The 64 strain gauges are different Switching between channels, strain acquis...

Abstract

The invention discloses a satellite-rocket unlocking separation wrapping tape pre-tightening force assessment instrument. The satellite-rocket unlocking separation wrapping tape pre-tightening force assessment instrument comprises a power module, strain gages, temperature compensation pieces, multiple option board cards, a strain collection board card, an AD collection board card, a central processing unit and a displayer. The option board cards realize switching, between different channels, of the strain gages of satellite-rocket unlocking separation wrapping tapes, and the strain gages of the selected satellite-rocket unlocking separation wrapping tapes are connected to the strain collecting board card to form a Wheatstone bridge. The satellite-rocket unlocking separation wrapping tape pre-tightening force evaluation instrument realizes the purpose of measuring satellite-rocket unlocking separation wrapping tape pre-tightening force through the Wheatstone bridge, automatic compensation of satellite-rocket unlocking separation wrapping tape pre-tightening force measuring environment temperature is realized, the measuring precision of the assessment instrument is improved, the measuring range of the assessment instrument is widened, the measuring function of the assessment instrument is improved, and the anti-interference performance, the reliability and the portability of the assessment instrument are enhanced.

Description

technical field [0001] The invention belongs to the field of industrial measurement, and in particular relates to an instrument for measuring the pretightening force of a star-arrow unlocking and separating tape. Background technique [0002] In the aerospace field, the satellite-rocket unlocking and separation tape is the core component of the connection and separation mechanism between the satellite and the rocket. Its function is to ensure that the satellite and rocket are connected reliably when the rocket is flying; after the rocket sends the satellite into the predetermined orbit, it ensures that the satellite and rocket are separated as required. [0003] In order to ensure the success of the space mission, the preload value and uniformity of the tape connecting the satellite and the docking mechanism must meet certain design requirements. If the pre-tightening force is too small, the purpose of locking cannot be achieved, and if the pre-tightening force is too large...
