Embodiment Construction

[0024] During the test, the test piece is fixed and tensioned by the test fixing module, and the test piece is loaded by the test loading module. The entire test device is a self-balancing structure and does not require additional constraints.

[0025] A strength test device for aerostat connectors, used to perform a separation strength test on a connector formed by thermal welding of the base cloth 1 and the connecting cloth 18. The device includes a fixed module at the bottom and a loading module at the upper part.

[0026] The fixed module tightens and fixes the edge of the base fabric 1 on the fixed stand 2; horizontal loading pulleys are also provided at different positions on the edge of the fixed stand 2;

[0027] The loading module fixes the pulley guide rail 13 above the fixed bench 2 through the loading platform 12, and a movable vertical loading pulley is installed on the pulley guide rail 13. The loading module also has an actuator 14 with one end of the cable connected to...

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, and in particular relates to a strength test device for aerostat connectors. Background technique [0002] There are a large number of typical connectors on the aerostat, such as a bow tie used to connect the cable to the capsule, and a cloth cover used to connect the keel to the capsule. These typical connectors must undergo a strength test 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 tensioned biaxially, 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 meet the requirements of different angles and different rates of loading. At present, there is no special test device specifically for the strength test of the typical connection of the aerostat. The existing test method All test...
