氢氧火箭发动机涡轮泵支撑结构随机振动分析对比

摘要

On the basis of previous turbopump support structure design experience, two simplified hinge and welding turbopump support structures are determined. The simplified structures are easy to calculate and compare. Strengths and weaknesses of them can be found more directly in random vibration environment. Finally, it reaches a conclusion that the hinged turbopump support structure of random vibration environment has more advantages.%在以往发动机涡轮泵支撑结构设计经验基础上，参考各型号发动机的相关结构确定出便于计算且相对简化的铰接与焊接涡轮泵支撑结构，简化后的结构相互之间更具可比性，可更直观地计算出两种结构在随机振动环境中的优劣。最后得出随机振动环境中基于关节轴承形式的铰接涡轮泵支撑结构更具优势的结论，可在氢氧火箭发动机中推广使用。
