【摘要】 将频域传递矩阵法应用于齿轮传动的扭振分析中，并导出了惯性元件、弹性元件及分布参数元件的频域传递矩阵。结合不同的边界条件给出了固有频率和固有振型的求解方法。更多还原

【Abstract】 Multi objective fuzzy optimal method could reflect the interrelation between individual objective optimal solution and multi objective optimal solution, take more factors into account simultaneously. In accordance with the multi objective characteristics of the installed capacity distribution of hydroelectric station group, this paper presents a multi objective fuzzy optimal approach to the distribution using fuzzy optimal theory, and tests its feasibility of this method by an example.更多还原
