Connection structure and connection system

Abstract

The invention provides a connection structure and a connection system, the connection structure includes a first connection body, which is provided with a connection through hole and a limiting through hole; a second connection body, which is provided with a tapered hole, a tapered hole, a limiting through hole Bit through holes and connecting through holes are distributed sequentially; tapered studs pass through the tapered holes, limiting through holes and connecting through holes, and the tapered studs have a first cylindrical part, a tapered part and a second connected in sequence. Cylindrical part; a conical fitting structure arranged in the limiting through hole, the conical fitting structure is provided with a first conical surface matched with the tapered part, and a limiting cylindrical surface matched with the inner wall of the limiting through hole; The tapered nut screwed on the first cylindrical part, the tapered nut is provided with a second tapered surface matching the tapered hole; the set nut screwed on the second cylindrical part, the set nut and the first connecting body The end surface facing away from the second connecting body abuts. Through the present invention, the technical problem that it is difficult to effectively transmit the vibration load to the aircraft or its sections in the vibration test of the large aircraft is alleviated.

Description

technical field [0001] The invention relates to the technical field of aircraft test equipment, in particular to a connection structure and a connection system. Background technique [0002] High-speed aircraft fly at a high speed and have a large mass, so they will bear a large vibration load during flight. In order to ensure the reliability of the aircraft structure, internal equipment and cables under vibration loads during flight, it is necessary to carry out ground vibration tests for the entire aircraft and aircraft sections for assessment and verification. In the ground vibration test, it is necessary to ensure that the vibration load borne by the aircraft structure, internal equipment and cables in the ground vibration test is not too large and the assessment is too strict, or too small and the assessment is insufficient. Therefore, the aircraft and aircraft sections, and vibration The transmission performance of the connection structure of the test adapter to the v...

Problems solved by technology

However, the ring clamp structure will achieve a tight compressive force on the connecting parts; while the size of large high-speed aircraft and its sections are large, and the outer heat-resistant structure of the aircraft cannot bear the additional compressive load, so , for large high-speed aircraft and its sections, such as the cabin structure, it is more difficult to connect with the ring clamp structure
