一种机液伺服车辆转向系统的设计与建模

摘要

Based on the need of the power steering system of a mining vehicle, a negative feedback closed loop control machinery⁃hydraulic servo steering system was designed, which had a good performance of simple structure, high dependability and easy to maintain. Then, mathematic models of the system were established, and the block diagram and transfer function were pro⁃posed. This provides theoretical basis for system performance analysis and optimal design.%根据某矿用车辆动力转向系统的需要，基于车辆转向动力学、机构设计和反馈控制原理，设计了一种结构简单、可靠性高、易于维护的机液伺服负反馈闭环控制转向系统。建立了系统的数学模型，得出系统的控制方块图和传递函数，为系统性能分析以及系统优化设计提供理论依据。
