Abstract

Facing the precise fast posture adjustment problems of aero-engine for their large dimension, heavy weight, low stiffness, small installation space, as well as high precision and high efficiency of assembly task requirements, a new 2-PRR planar parallel mechanism is proposed to meet the elevation and inclination work in the automatic installation process for aero-engine, which is carried out by kinematics analysis to prove its feasibility. Applying multi-rigid system dynamics theory, its dynamic model is established and analyzed under working conditions of high inertia, high eccentric load to do a comparative analysis on the force process trends of each component during four work postures: original position, left inclination, right inclination, vertical elevation. According to the analysis results, conduct structural design and establish the multi-degree elevation and inclination posture adjustment platform, which reaches the high motion precision level of posture adjustment in the experimental accuracy test with eccentric load and error optimized compensation to provide a significant foundation on further development of a new multi-degree, automatic precise equipment for aero-engine installation.
