摘要: 为了深入了解拉杆预紧失谐对组合转子动力学特性的影响,建立考虑界面粗糙度的组合转子预紧失谐模型,研究预紧失谐下组合转子动力学特性.在此基础上,分析拉杆预紧失谐对组合转子结构强度的影响.研究结果表明:与预紧谐调相比,正、负失谐均引起组合转子振动加剧;转速越大、拉杆数目越少、轮盘级数越多,转子不平衡响应越大.拉杆预紧负失谐时转子最大应力与预紧谐调时相当,拉杆预紧正失谐对转子强度影响显著,失谐使得轮盘界面的最大应力增加.
关键词: 失谐组合转子不平衡响应结构强度    
Abstract: In order to have a good knowledge of dynamic characteristic for combined rotor considering preload mistuning, the preload mistuned dynamic model of combined rotor considering interface roughness was established, and the effect of rod preload mistuning on dynamic characteristics of the combined rotor was studied. Then, the influence of rod preload mistuning on stress distribution was obtained. The results showed that vibration increasement was caused by preload force mistuning and the greater of rotor unbalance response with the faster of velocity, more of disk stages and fewer of rod number. The stress distribution of negative mistuning was the same as preload tune condition, whereas the positive mistuning had great effect on structure strength for combined rotor. The maximum stress increased which was caused by mistuning.
Key words: mistuning    combined rotor    unbalance response    structural strength
