摘要
六自由度轴耦合道路模拟试验台是一种结构复杂的串并联结构,杆系的特殊布局和结构尺寸设计,使得只有在一个或者是两个液压缸做主动运动时就能实现台架在某个自由度上的运动。但是在大行程工况下,主要驱动液压缸和其余液压缸之间存在着比较大的耦合。以轴耦合道路模拟试验台的一个角为研究对象,在逆运动学分析的基础上,对单自由度运动时各杆系之间耦合程度的大小进行了分析,得出了在不同自由度运动时主要产生耦合运动的杆系。
The 6-DOF spindle-coupled road simulators arecomplicated serial-parallel mechanisms,the special layout and structural dimension make it possible to make mobile platform complete the motion of single degree of freedom only when one or two hydraulic cylinders moving. However,in the case of large stroke,there is a relatively large coupling between the main hydraulic cylinder and the other hydraulic cylinders. One corner of 6-DOF spindle-coupled road simulators has been investigatedand the degree of coupling between the rods at single degree of freedom is analyzed emphatically on the basis of inverse kinematics analysis.As a result,the rod which produces the coupling motion mainly at different degrees of freedom movement is obtained.
