Description

Technical Field

[0001] The present invention relates to the technical field of aerospace vehicle launch, and particularly to a multi-station main and auxiliary frame connection device and a modular connection method. Background Art

[0002] Generally, a single main frame is used to carry the upper load on the vehicle launch platform. However, when multiple types of upper loads are loaded on one platform, in order to meet the requirements of multi-load joint loading, multiple tasks, and mixed loading of multiple loads, the design structure of the main frame of the vehicle launch platform is often very complex. In order to reduce weight, reduce design costs, improve loading convenience, loading adaptability, and increase load capacity, the main and auxiliary frames are used to carry different upper loads respectively.

[0003] Regarding the connection method between the main and auxiliary frames, the screw connection method is usually used. However, on the one hand, the frame span is large, the number of screws is large, the disassembly and assembly difficulty is very high, the disassembly cost is high, and the connection rigidity is poor; on the other hand, for the marching use of a large vehicle with a wide width (close to the railway clearance limit), the main and auxiliary frames need to meet the marching size limit. In the case of an over-width vehicle body, the main and auxiliary frames often need to be transported separately, and the transportation cost is very high. Summary of the Invention
