摘要
本文运用概率分析方法,把轴系中各构件的固有频率和激振力频率视为随机变量,基于轴系的特定结构与受力条件,分析机械结构中各构件的固有频率分布函数和激振力频率的分布函数,建立起轴系设计的动态可靠性模型,计算出轴系设计的动态可靠度,为轴系的结构设计提供理论依据。
The probability analysis was used in this paper.Natural frequency and of excitation force frequency of every component in shafting system were considered to be the random variable.The distillation functions of natural frequency and of excitation force frequency were analyzed on the basis of special structure and stress conditions.The dynamic reliability model of the axis was set up and dynamic reliability of the designed axis was worked out to provide the reference for structure designing of axis.
