摘　　要：针对多轮重型车辆用中心臂连杆转向机构的设计进行了分析与研究。基于运动学原理以及车辆转向阿克曼原理,提出了该转向机构的解析设计方法,建立了等长约束方程,由切贝雪夫间隔确定了精确转向角,并编制了相应的设计计算程序,从而实现了对其尺寸参数的解析求解。在此基础上,利用ADAMS仿真软件对由此设计的单相和多相转向机构分别进行了运动学仿真与转向误差分析,结果证明转向效果基本满足阿克曼原理,验证了方法的正确性。We present the design and analysis of a center-arm-linkage-type steering mechanism of heavy vehicle with multiple wheels. The design method for the center-arm-linkage-type steering mechanism is proposed based on the kinematic synthesis and Ackerman principle. With the help of constraint equation and the Chebyshev spacing, the geometric dimensions of all linkages for this type of steering mechanism can be obtained by the method. The simulation results in ADAMS show that our method is feasible and efficient and can be used in the design of many kinds of heavy vehicles with multiple wheels.
