As all-electric aircraft has many advantages, aircraft nose wheel steering system would be developed to the all-electric direction. 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 composed of a nose wheel steering mechanism of two worm gear and a control servo system of fly-by-wire having both steering and anti-shimmy function is designed to meet the demand for operation control in nose wheel steering system. Then based on LMS-AMESim software, the simulation model of the system is established to make the dynamic simulation analysis for the verification of its steering function. The simulation results indicate that the nose wheel steering system is reasonable, and can meet the requirements of the general project. Then the prototypes of the steering mechanism and control system are researched to validate the design and the steering test bench is prepared to test the system working. The test results, such as steer angle, rotate speed of motor are analyzed in details and compared with the theoretical results. The results show that the design is reasonable and the property of the prototype achieves the design objectives.
