摘要(Abstract):

对整体齿轮增速型H81 1离心压缩机第三级转子进行了临界转速的数值计算 ,分析了拉紧螺栓结构特殊性、齿轮传动力和支座刚度等因素对转子临界转速的影响 ,同时探讨了拉紧螺栓的计算建模方案问题
The numeric calculations are carried out on the third stage rotor of the H81 1 centrifugal compressor with integral speedup gears, the effect of structural particularity of tense bolts, gear driving force and support rigidity on critical aped of the rotor is analyzed and the computational modeling scheme for tense bolts is investigated.
