英文摘要：

As all-electric aircraft has many advantages, the all-electric aircraft nose wheel steering system would be developed. Aiming at the control demand of nose wheel steering system, based on the basic principles of nose wheel steering system and the design technique of mechanotronics, an all-electric aircraft nose wheel steering system is designed to meet the demand for operation control in nose wheel steering system, the system is composed of a nose wheel steering mechanism of turbine worm and a control servo system of fly-by-wire having both steering and anti- shimmy function. The simulation model of the system is established to perform the optimization of dynamic proper- ties and dynamic simulation analysis for the verification of its steering and shimmy damping function. The results in- dicate that the nose wheel steering system is reasonable and validated, and it can meet the requirements of the gen- eral project.
