This paper directs the special problem of rigid rotor existing in running under high speed. Based on basic theories of dynamics and gyrostatics, this paper gives out effective measures and structure design criterion to meet high speed of rigid rotor in engineering practice. 本文针对刚性转子在高转速工况时所具有的特殊问题,建立在转子动力学、陀螺力学等基本理论基础上,提出了使工程实际中应用的刚性转子适应高转速的有效措施和结构设计准则。
