Aero- engine vibration visualization simulation technique is the important part of the whole machine vibration and analysis, Using dynamic display simulation and experimental data, we can dynamically observe the rotor system vibration,the change rule of rotor- stator clearance and the locations rubbing,and thereby more easily evaluate engine vibration state, diagnosis engine vibration faults. In order to stand out the visual focus of the whole machine vibration, and the object - oriented method is used to establish the aero - engine visual components and whole machine model, which is easier to model and modify, and at the same time,the data is used to drive animation model,and it displays aero- engine machine vibration.%航空发动机整机振动可视化仿真技术是整机振动与分析的重要组成部分,通过将计算仿真和实验数据进行动画显示,可以动态地观察到转子系统的振动,转静间隙的变化规律,以及容易产生转静碰摩的部位,从而更加方便地评估发动机振动状态,诊断发动机故障.为了突出整机振动可视化重点,依据有限元梁模型构建二维显示模型,并基于面向对象的方法,建立了航空发动机可视化的部件与整机模型.模型的建立与修改方便容易,同时利用仿真数据驱动动画模型,直观有效地展示了航空发动机整机振动过程.
