摘　　要：提出的新方法将阶梯轴分为若干段，每段可视为等截面轴，每段内所满足的扭振混合状态方程可精确地求出，然后利用两段之间的连续条件和边界条件将固有频率求出。In this paper, a stepped shaft is divided in to several segments, and each segment can be regarded as one with identical cross section.The torsional vibration mixed state equation can be solved exactly for every segment, then the natural frequency of the shaft is obtained by using continuous condition between two segments and boundary conditions.[ZK)〗

关 键 词：阶梯轴 扭转振动 混合状态方程 固有频率
