摘　　要：基于三维全息谱思想,利用计算机图形学方法,研究航空发动机转子工作弹性线测试及可视化技术。在高速动平衡试验机上,针对航空发动机真实高压转子进行转子弹性线测试和可视化研究,分别在不同平衡状态下测取了转子工作弹性线,实现了转子弹性线的动态显示。研究表明,转子不平衡量对转子工作弹性线的大小和形状具有重要影响,转子弹性线测试与可视化技术可作为转子平衡状态的有效评估方法和手段。Based on the three-dimensional holospectrum, the measurement and visualization technologies of rotor working elastic curve were studied by means of the computer graphics. On one high-speed dynamic balancing machine, rotor working elastic curves of a real high-pressure rotor of an aero-engine were mea. sured and visually studied. The curves for different balance conditions were recorded to achieve dynamic display of rotor elastic curve. Results show that the rotor imbalance has an important effect on the magni. tude and shape of the rotor working elastic curve, and the measurement and visualization technology of the rotor working elastic curve is an effective evaluation method for rotor balancing state.
