Exploiture Design And Simulation Research On Flexible Assembling Fixture For Panel Component

Aircraft assemble is based on the coordination principle of dimension, in accordance with the design and technical requirements combination of aircraft parts or components form a higher-level assembly or machine process. So far, aircraft assembly technology has evolved the development history from manual assembly, semi-automated assembly to automated assembly. At present, the rapid development of flexible assembly makes the automated assembly technology to a new level.This thesis based on the development project of aircraft typical panel component assembly process equipment systems. After had analyzed the assembly process of the panel component, this thesis proposed a new techniques and method for panel component assembly--adaptive positioning flexible fixture technology. It was composed of the following parts:First, this thesis in-depth study the developments in the field of the flexible assembly and related research, explained the purpose and significance has been raised by project, clearly the main content of this research project.Next, based on the working principle and motion characteristics of Coordinate-driven, the CATIA software was used as supporting platform to study the digital, modular design, assembly simulation and interference checking of the Flexible Fixture Tooling (FFT). The result verified the geometric parameter design of FFT rationality. Utilizing the virtual prototype technology and ADAMS software, kinematics, dynamics mode for FFT was established and a simulation analysis was carried out, and explored main factors that affect the kinematics, dynamics properties and its effects. The static stiffness and dynamic characteristics(Natural Frequency and Modal) of FFT researched by using the function modules of Statics (Static function module is used to solve the FFT's deformed and stress caused by external load) and Structural Dynamics(Dynamics function module is used to solve the FFT's natural frequencies and modal) in ABAQUS software.Finally, we have a conclusion on our work, get some useful conclusions and propose the next to do. With analysis and comparison, this thesis proposes some improving measures for FFT structural design. It has certain reference value to the development of aircraft typical panel component assemble process equipment systems.
