摘要/Abstract

摘要： 针对三维叶片时域流固耦合振动响应计算普遍耗时的问题，采用一种假设整体结构的模态位移，求解固体时域响应和实现高效网格变形，发展了一种3维时域流固耦合分析的整体弹性结构方法，并应用于压气机叶片0°和180°相位角的气动稳定性分析中。结果表明，所发展方法的计算结果与传统双向时域算法和文献的结果较为吻合，而计算效率相比于传统算法显著提升；在所分析的两个相位角下，叶片振动的气动阻尼均随流量减小先增大后降低，相比于0°相位角，180°下叶片的气动稳定性大幅提高，表明该方法能有效应用于叶片的工程流固耦合研究。

Abstract: For the general time-consuming problem of 3D time-domain blade vibration calculation by fluid-solid coupling, the modal displacement of a kind of hypothetical global structure is adopted to calculate the time-domain response of solid and complete the fluid mesh deformation effectively, so a Global-Elastic-Structure method for 3D time-domain fluid-solid coupling analysis is developed, which is applied to the aerodynamic stability analysis of compressor blades on 0° inter blade phase angle (IBPA) and 180° IBPA. The results show that the calculated results by the proposed method are mainly consistent with those of traditional two-way time-domain method and literatures, while the calculation efficiency improves significantly compared to the traditional method. On the two IBPAs involved, the aerodynamic dampings of blade vibration both increase first and then drop with the decrease of the flow-rate, the aerodynamic stability of the blade on 180°IBPA is greatly improved compared with that of 0°IBPA, indicating that the proposed method can be effectively applied to the engineering fluid-solid coupling analysis of blades.
