Small celestial body penetration anchoring test platform and test method thereof

Abstract

The application discloses a small celestial body penetration anchoring test platform and a test method thereof. The test platform comprises a main structure, a simulated asteroid container, a launching unit, a speed meter, a camera, a force steel wire, a tension meter, a rocker arm, and a rocker arm support. The launching unit comprises a mounting plate, a base, a launching cylinder, a piston, a cartridge, a ejector pin, a recovery spring, an electromagnet, an anchor body, a buffer pad, a flange, an ejector pin support, and a pose adjustment groove. The cartridge is internally provided with air holes, so that the penetration depth, the penetration trajectory, and the anchoring force of the anchor body in different speeds, different penetration angles, and layered asteroid soil can be tested. The anchor body penetration power is provided by a blank cartridge, and the blank cartridge is triggered by the electromagnet hitting the ejector pin. The application has the characteristics of high test efficiency, full test coverage elements, low cost, safe and simple operation, and the like.
