| Accompany with the overall rapid economic development of our country and the progress of the civil aviation, aviation transport turnover volume, passengers and cargo traffic has recorded higher. Aircraft tire need to withstand severe friction and wear in the process of the aircraft taking off and landing. Correspondingly the times of tire replacement are more frequent based on the requirement of flight safety.The volume and quality of Aircraft tire is large, many aviation companies and maintenance departments in the domestic often use simple tooling equipments to deal with the separation of aircraft tire body and wheels, or use tooling equipments abroad to solve. But along with the continuous development of civil aviation, simple equipment can’t satisfy the increasing workload of tire replacement on the working efficiency in the relevant companies. At the same time, the price of the equipment imported by overseas is more expensive. In view of this, we intends to develop a device which function is outstanding, suited to many domestic civil aviation airport and related companies.The Aircraft Tire Beadbreaker is as the design and research target in this paper using the idea of virtual design and computer aided technology, taking advantage of the excellent CAD/CAE software platforms to complete product design and analysis in order to guide the design of physical prototype.The main content researched in this Paper is as follows:The first chapter expounds the present development situation of the Aircraft Tire Beadbreaker at home and abroad, expounds how to make use of computer aided technology to study the Aircraft Tire Beadbreaker, puts forward this topic research content of the papers and the analysis and research work.The second chapter puts forward the design of conceptual model of the Aircraft Tire Beadbreaker using Pro/E software to complete the structure and function design of product, puts forward the driving mechanical structure using hydraulic system, describes the typical circuits of the hydraulic system in the application of this device which mainly introduces the design method of multi-cylinder synchronization system to complete different structures in the Aircraft Tire Beadbreaker and how to use PLC to control the whole system.The third chapter puts forward how to make use of finite element analysis and design optimization based on the finite element simulation software such as ANSYS to check the strength and optimize the product structure of work done with the key shaft components of the Aircraft Tire Beadbreaker as an example.The fourth chapter introduces how to use the finite element simulation software ANSYS to analyze the nonlinear deformation process in the action of the roller pressuring aircraft tire, the appropriate load of roller is guided according to the deformation degree of the tire, and obtains the suitable roller structure size by using Design Explore.The fifth chapter discusses hydraulic system for upgrade, proposes how to use the electro-hydraulic servo valve, electro-hydraulic proportional valve to replace ordinary valve, establishes the simulation environment by AMESim, illustrates how to study the upgraded electrohydraulic synchronization control system checked by position.The sixth chapter summarizes the full text of the main research work and achievements, further research work and the direction in the future. |
