摘要
基于三轴车辆全轮转向系统方案,设计相应的转向传动机构,建立了该机构的数学模型,并通过MATLAB软件中的非线性优化命令进行设计计算。计算结果表明,由该机构所决定的转向曲线与理论阿克曼曲线能较好吻合。且车轮理论与实际转角误差较小,有较高运动精度。同时,该机构能够很好地与转向液压系统配合,进而实现对车轮转角的实时精确控制。
Based on the plan of all-wheel steering system for three-axle vehicles, the corresponding steering linkage mecha-nism is designed, the mathematic model ofthe mechanism is established, and design and calculation are also carried out by u-sing the nonlinear optimization command in MATLAB.The result shows that the mechanism′s steering curve can well fit the theoretical Ackermann curve, and the error between the wheels′theoretical and practical steering angles is relatively small, thus presenting a high precision.In addition, this mechanism can well cooperate with the hydraulic steering system and thus can help to realize the real-time accuracy control of wheels′steering angle.
