Title Design of locking mechanism for  connector for connector with charging connector
Abstract
The thesis studied the application and development of rocket fuel charging connector, combined with the existing various principles of the charging connector design, proposed the mechanical mode based on the clutch jaw mechanism.
The main body of the structure is based on the four-bar mechanism, which driven by pneumatic cylinder push rod.By the way of mapping, and the relationship of all institutions in a particular location. Determine the layout of the overall structure, member of range of motion, bars interference fan, on this basis to determine the size, complete the size selection and design drawing. The dynamic characteristic and the strength of the key parts of the design mechanism are analyzed by the dynamic analysis and the finite element analysis. 源`自*六)维[论*文'网www.lwfree.cn
