【摘要】 以独特的、自行设计的支承刚度可变的多功能模拟轴系为具体的研究对象,对百万千瓦级汽轮发电机组的动力特性进行分析。在动力特性分析中,采用“传递矩阵法”和本文所提出的在传统的影响系数法的基础上推广的“广义影响系数法”,编制了传递矩阵法的计算程序及广义影响系数法频率方程求解的计算机程序。更多还原

【Abstract】 In this paper, we set the self-designed multifunctional simulating shafting with changeable support stiffness as our study subject and make a close analysis of the dynamic feature of the million-kilowatt-class turbogenerator. For analyzing the dynamic features, we use two calculating methods. One is the transfer matrix method and the other is the generalized influence coefficient method on the basis of traditional influence coefficient method. Also, we make the computer programs of transfer matrix method and frequency equation of generalized influence method.更多还原
