In order to automate the ground maneuvering of a civil regional aircraft and improve the efficiency of the air transport system, a fly-by-wire nose wheel steering system (NWSS) was designed. A rack and pinion steering mechanism integrated with a single actuator mechanism was proposed. The basic control circuit diagram with integrated test, the electro-hydraulic system diagram, and the mathematical model of the steering system were established and analyzed. A co-simulation model of the system was built to verify the control law. The results show that the properties of the prototype meet the design requirements. Given the importance of the NWSS, the simulation results can be used to optimize the basic design parameters. This methodology can also be used for other types of aircraft.

为了实现民用支线飞机的地面机动自动化，提高航空运输系统的效率，设计了电传前轮转向系统（NWSS）。提出了一种与单个执行机构集成的齿轮齿条转向机构。建立并分析了集成试验的基本控制电路图、电液系统图和转向系统的数学模型。建立了系统的联合仿真模型来验证控制律。结果表明，样机性能满足设计要求。鉴于 NWSS 的重要性，仿真结果可用于优化基本设计参数。这种方法也可用于其他类型的飞机。
