Abstract

Abstract A novel separating device, Inertial particle separator (IPS), has been developed recently to separate solid particles and to protect the turbine engine from particle erosion damage. Herein first, an advanced model based on IPS was proposed to investigate the deformational behavior of deformable particle separator, and to meet the higher requirements of sand discharge and pneumatic demand, which are operated under hostile working conditions or environments and severe climate conditions. We established a three-dimensional (3D) nonlinear finite element analysis (FEA) model of bump consequently, which was the core of centerbody. The essential material parameters of the FEA model were obtained via experimental data (tensile testing). By comparing the influence of these factors (pressure and laying angle), the deformational behavior of the centerbody was discussed. Finally, based on the simulation results with the experimental data (Schlieren testing), the model was found to perform with high reliability and accuracy, demonstrating the great capability in precisely predicting the deformational characteristics of the bump under practical working environments.

基于有限元分析和实验验证的橡胶复合材料变形行为

摘要最近开发了一种新型的分离装置，惯性颗粒分离器（IPS），用于分离固体颗粒并保护涡轮发动机免受颗粒侵蚀损坏。本文首先提出了一种基于IPS的先进模型，以研究可变形颗粒分离器的变形行为，并满足在恶劣的工作条件或环境和恶劣的气候条件下运行的排砂和气动需求的更高要求。因此，我们建立了作为中心体核心的凸块的三维非线性有限元分析模型。有限元分析模型的基本材料参数是通过实验数据（拉伸试验）获得的。通过比较这些因素（压力和铺设角度）的影响，讨论了中心体的变形行为。最后，基于模拟结果和实验数据（纹影检验），发现该模型具有较高的可靠性和准确性，证明了在实际工作环境下准确预测凸块变形特性的强大能力。

期刊介绍： Science and Engineering of Composite Materials is a quarterly publication which provides a forum for discussion of all aspects related to the structure and performance under simulated and actual service conditions of composites. The publication covers a variety of subjects, such as macro and micro and nano structure of materials, their mechanics and nanomechanics, the interphase, physical and chemical aging, fatigue, environmental interactions, and process modeling. The interdisciplinary character of the subject as well as the possible development and use of composites for novel and specific applications receives special attention.
