航空发动机中,有很多故障是由于榫联接构件在微动环境下失效引起的,进而造成了叶片和盘的损伤和破坏,因此研究榫联接结构的微动疲劳有重要的工程应用价值。 - Further more , the fracture possibility is analyzed with fracture mechanics after the stress calculation of local high stress area around the bolt hole in shell flange and the measurement of fracture toughness of gray cast iron . the improving structure of bolts connected head and shell flange is brought forward
此外,在计算获得缸体法兰螺栓孔局部高应力区的应力水平后,由断裂力学分析发生脆性断裂的可能性,并提出烘缸缸体与缸盖联接结构的改进方案。 - First , the theory of fretting wear and studies on fretting fatigue were introduced and the parametric method was used in the process of creating the model of dovetail joints in ug software . the elastic contact problem is analyzed in finite element method ( fem ) and is used to the parameters " distribution and contact stress of the joint are obtained on the base of ansys code . with the effect factor of load frequency , the prediction method of fretting fatigue life of dovetail joint under low and high / low cycle complex load is proposed
本文介绍了微动损伤的机理和微动疲劳寿命的研究方法;利用ug软件对燕尾榫联接结构创建了参数化实体模型;基于ansys软件平台求解弹性接触问题,获得了榫联接结构接触应力及接触状态量的分布;在已有微动疲劳寿命预测模型的基础上,引入载荷频率影响因子,对低周、高低周复合载荷作用下的燕尾榫联接结构进行了微动疲劳寿命的预测,与试验结果对比表明采用本文提出的方法预测榫联接结构的微动疲劳寿命是有效的。 - ( 3 ) the transformation for turbo cycling compressor is designed in both differential pressure seal parts at the inlet and outlet and the connecting construction of the positioning key and turbo cycling compressor casing : replace wave pipe of differential pressure seal parts with asbestos jointing and improve its reliability ; jointing connection of the positioning key and turbo cycling compressor casing has been converted into screw thread connection and avoid the dangers from jointing crack
( 3 )从进出口压差密封部件和定位键与外壳间联接结构两方面入手,提出了相应的改造方案:将机组进出口压差的密封部件由波纹管改为石棉填料函,提高了其运行可靠性;将内件周向定位键与外壳间的联接结构由焊接改为螺纹联接,避免了焊接裂纹引起的安全事故。
