运用有限元软件ABAQUS对叶轮进行模态及静力学的模拟分析,得到了叶轮的固有频率、模态振型等主要参数及叶轮的应力、位移分布云图,对叶片工作状态时的动态性能研究及叶轮的运行可靠性分析具有很好的指导和参照意义。
The finite element software ABAQUS was used to simulate the impeller in modal and statics. The main parameters such as the natural frequency and mode shape of the impeller and the cloud distribution of the stress and displacement of the impeller were obtained. And the dynamic performance of the impeller was analyzed. Impeller operation reliability analysis has good guidance and reference.
