Investigation On Dynamics Simulation Of Ground High-speed Taxiing System Based On Virtual Prototyping

High-speed taxiing device is a kind of important experimental facilities in the aircraft dynamic ground test system which consists of thruster, force undergone platform, slide rail, and the relevant braking device. The costs of the ground tests by use of the facility are reduced, and it has a greater flexibility than that in the practical air flight tests.Firstly, the feasibility of the high-speed taxiing device based on the techniques of compressed gas powered propulsion is observed, the numerical results propose the optional approaches and parameters to the propulsion system design afflicted to the drop test bench for the carrier based aircraft. Secondly, a rigid-flexible coupled model of the ground high-speed taxiing system is established utilizing MSC.ADAMS and MSC.PATRAN/NASTRAN software, the dynamic analysis and simulation to the high-speed taxiing device are conducted based on the virtual prototyping techniques, the impacts on the system dynamic properties and their variational tendencies are analyzed under the different parameters. The parametric analysis method is proposed, and the optimization design of the system structure is implemented. Lastly, the strength and the modal analysis are researched using the Finite Element Method which ensures enough strength of the platform, and the natural frequency of the system is obtained. The conclusion obtained provides a good basis for the further structural optimization.It may has a significant value as a reference for the obtained results and the methods employing virtual prototyping for the ground high-speed taxiing system, such as in the fields of the structural design and performance research of the high-speed taxiing device, since it not only improves the design efficiency greatly, but also shorten the cycle of product design.
