Design And Mechanical Simulation Of Fine-tuning Device In Flexible Docking Tooling Of Compartment

In recent years, with the rapid development of our country’s aerospace business, the workload of each type of compartment docking is increasing. In order to achieve rapid assembly of different type of compartment, it’s necessary to develop a set of mechanical and electronic integration flexible tooling,that can be applied to assembly different type of compartment. Because it’s need to make manual fine-tuning to achieve assembly of compartment after the preliminary orientation, designing manual fine tuning device of compartment flexible tooling has important practical significance. This paper designs manual fine tuning device according to the actual demand of docking assembly. CATIA software is applied to modeling designed device, and ANSYS Workbench software is applied to make mechanical simulation analysis of designed device, in order to make sure the designed manual fine-tuning device meets the requirements of strength.Firstly, this thesis introduces the theory and design principles of mechanical design, in order to provides the basic direction and theoretical support for the design of manual fine-tuning device. The related software is introduced, including the CATIA three-dimensional modeling software and ANSYS Workbench finite element analysis software. The technology of structural nonlinear analysis in simulation analysis is researched. Especially the technology of contact nonlinear analysis is researched to provides technical support for mechanics simulation analysis of manual fine-tuning device.Secondly, several schemes of three degrees of freedom manual fine tuning device that meet the demand of the actual docking assembly are provided, based on the existing compartment flexible tooling. The comparison of these schemes is made, according to principles of mechanical design, in order to determine the final schemes of manual fine-tuning device. Then the size of manual fine-tuning device and engineering drawing are designed.Thirdly, static simulation analysis of truncated cone spiral spring in switching and lifting fine-tuning device is made to verify the structural nonlinear characteristics. The dynamic simulation analysis is made under the specified dynamic load. Then design of structure is improved according to the simulation results, and the effectiveness of theimproved structure is verified.Finally, static simulation analysis of key components of horizontal fine-tuning device is made to make sure the security of designed structure. And modal analysis of gear clutch driving device in horizontal fine-tuning device is made to make sure its security in the motor driving and manual driving condition.
