Abstract

The invention belongs to the field of aerostat testing, and in particular relates to a strength testing device for a connector of an aerostat. There is currently no special test device specifically designed for the strength test of a typical connector for aerostats. The object of the invention is to change the disadvantages such as large field occupying, low installation efficiency, long test period, and poor repeatability in the existing test methods. A fixing module tightens and fixes the edge of a base fabric on a fixing gantry; horizontal loading pulleys are further disposed at different positions of the edge of the fixing gantry; a loading module fixes pulley rails above the fixing gantry through a loading gantry, and movable vertical loading pulleys are mounted on the pulley rails; the loading module further has an operating cylinder, one end of the cable is connected to the operating cylinder, and the other end is connected to the connecting cloth via the loading pulleys, thereby realizing the automation of test installation and loading, and greatly improving the test efficiency. The test device is automatically controlled by programs from installation to loading, which greatly improves the test efficiency.

Description

technical field [0001] The invention belongs to the field of aerostat testing, in particular to a strength testing device for aerostat connectors. Background technique [0002] There are a large number of typical connectors on the aerostat, such as the bow tie used for the connection between the cable and the capsule, and the cloth cover used for the connection between the keel and the capsule. These typical connections must be strength tested on the ground. During the strength test, in order to simulate the real situation and meet the relevant test standards, the base fabric of the test piece should be biaxially tensioned, and the loading requirements of different angles and different rates should be met. This requires a test device that can quickly tension the test piece and can meet the loading requirements of different angles and different rates. At present, there is no special test device for the strength test of the typical connection parts of aerostats. The existing ...
