Abstract:In order to investigate the deformation of parts during the movement of variable inlet guide vane (VIGV) actuation systems and the effect of deformation on adjustment accuracy and consistency, the flexible and rigid multi-body dynamic 3D models of VIGV actuation systems were established in the commercial package ABAQUS. The difference between flexible and rigid body models was studied, and the deformation effect on vane angle adjustment was analyzed. On this basis, the effects of radial limit of unison ring, driving loading rate and friction of kinematic pairs on VIGV actuation systems were analyzed. It is found that the analysis results of the flexible and rigid models are basically same under a small adjustment angle. While, with the increase of the adjustment angles, the influence of part deformation is gradually enhanced, when the L-shaped rod is rotated by 0.5 rad, the difference of adjustment angle is about 0.9。 between two models. In the adjusting process, the frictional augment will need more force to drive the systems, and the loading rate can be ignored in a certain range. Meanwhile, the cancellation and uneven distribution of unison ring radial limit will cause the inconsistency of vane adjustment angles, the maximum difference of adjustment angles between lever arms is about 0.3°under unison ring radial limit is cancelled.
