摘要
铰链四杆机构中的RRR二级杆组可能存在2种装配模式.运用几何学中三角形三边长的关系对铰链四杆机构中RRR杆组的装配模式进行探讨,得到铰链四杆机构中的RRR杆组两杆件共线的条件,进而结合Grashof条件得到了各种铰链四杆机构死点存在情况及在整个运动过程中RRR杆组装配模式发生变化的可能性.
There is likely to be two kinds of assembly modes of RRR Assur group in a revolute four - bar mechanism. The assembly modes of RRR Assur group in a revolute four - bar mechanism is discussed by applying the triangle inequality. Then the collinear condition of the two links of RRR Assur group in a revolute four- bar mechanism is found. Furthermore combined with Grashof conditon, the dead points and the diversification possibility of RRR Assur group in all kinds of revolute four - bar mechanisms are found.
