Abstract:

A set of tooling equipment which can remove and install landing gear has been designed,which can realize the function of multi degree freedom adjustment,making the procedure more convenient. Positioning through two traction holes on the landing gear will not cause damage to the landing gear itself;however,it can shorten the assembly working time and improve the reliability of disassembly and assembly work. The positioning base position is adjustable and has strong commonality,realizing different types of landing gear assembly and disassembly. The 3D digital model of the new dismantle and assemble equipment is built with CATIA. Firstly,the proper joints are added with DMU module,then the kinematic simulation is analyed. The results provide theoretical evidence for the design of new dismantle and assemble equipment.
