摘要/Abstract

摘要： 为了研究带有安装边螺栓连接结构的机匣对断裂叶片的包容能力，截取环形机匣中的安装边螺栓连接结构，开展有限元仿真和冲击试验。首先，使用LS-DYNA软件建立有限元模型，研究撞击角度、撞击位置、定距套和止口对机匣安装边螺栓连接结构抗冲击能力的影响。仿真结果表明：撞击位置、撞击角度、定距套和止口都对结构的抗冲击能力有显著的影响，当叶片撞击在单侧机匣的安装边位置时结构的抗冲击能力最弱，定距套和合理的止口设计都能够有效提高结构的抗冲击能力。然后，通过机匣安装边螺栓连接结构的抗冲击试验，验证了数值仿真方法的准确性和可靠性，为数值仿真结论的有效性提供了依据。最后，通过数值仿真分析了螺栓断裂过程，并结合试验分析揭示了螺栓发生剪切断裂和拉伸断裂的原因。

Abstract: To investigate the blade containment of casings with bolted flanges, finite element simulations and impact tests are carried out with the bolted flange structure cut from the whole casing. LS-DYNA is used to create the finite element models to study the effects of the impact angle, impact position, sleeve and rabbet on the impact resistance of the bolted casing flange structure. The simulation results reveal that the impact angle and impact position have remarkable influence on the impact resistance of the bolted casing flange structure, which is the weakest when the blade impacts on one side of the flange. Adding sleeves or proper rabbets in the bolted casing flange structure increases the impact its resistance. The accuracy and reliability of the simulation results are then validated by the impact resistance tests of the bolted casing flange structure. Analyses of the fracture process of the bolts based on simulation and test results reveal the origin of tensile and shear fractures among the bolts.

Key words: casings, bolted joints, containment, finite element simulation, impact resistance test
