摘　　要：重型运输车外形尺寸大,往往需要多轮甚至全轮转向,以便减小转弯半径。为了降低轮胎摩损,提高方向控制的平稳性,要求转向连杆机构有较高的传动精度。SolidW orks软件具有几何约束和尺寸驱动等参数化设计功能,且与Excel软件无缝兼容。在SolidW orks软件中建立动态模型,并采用作图法,结合Excel软件的数据处理及图表功能,考核目标值,找出其变化趋势,通过优化分析得到合理的机构铰点尺寸。确定机构后,再利用转矩平移原理,建立机构杆系的数学模型,在Excel软件中采用枚举法求极限值,计算出机构中各类力学数值,设计机构合理的尺寸。The heavy-loaded transportation vehicle has huge outline dimension,usually,the multi wheel even all wheel steering are required for reducing the turning radius.To minimize the abrasion of tyre and improve the stability of directional control,the transmission precision is high demand for steering connecting rod.Solidworks software has the parameter design function of geometry limitation and dimension driver,which is compatible to Excel.To make dynamic model,adopt drawing method,combine with data process and graphic function of Excel,inspect the required value,find out the changing way,through analysis to get the reasonable dimension of structure hinge point.After making sure of structure,adopt torque translation theory to make the mathematic model of structure rod,calculate the ultimate value by enumeration method,to calculate vary mechanical value,design the suitable dimension.
