并联机构的运动伪奇异分析

To solve the problem of whether or not singularity when moving platform rotating around second moving shaft of a moving coordinate system at 0or 90,the movement pseudo singularity of a parallel mechanism is analyzed.Combininging a Stewart cross-legged parallel mechanism,under the condition of moving...

description To solve the problem of whether or not singularity when moving platform rotating around second moving shaft of a moving coordinate system at 0or 90,the movement pseudo singularity of a parallel mechanism is analyzed.Combininging a Stewart cross-legged parallel mechanism,under the condition of moving platform rotating around second moving shaft of a moving coordinate system at 0,the movement pseudo singularity of a parallel mechanism produced by z-y-z Euler angle is introduced.From aspects of a rotation angle around a moving shaft and moving coincidence shaft,the reason and location of movement pseudo singularity are analyzed.It is presented that reason of movement pseudo singularity is that description of parameter differential of a moving platform degenerates from angles of rotating around three moving shafts to angles of rotating around two moving shafts.Coincidence location of first-end moving shaft of 12kinds of Euler angle is location of movement pseudo singularity of a parallel mechanism.
