| 摘 要： | 基于齿轮动力学模型建立了齿轮传动系统耦合振动的可靠性模型,解决了齿轮耦合振动的可靠性分析和可靠性灵敏度分析的问题.将齿轮系统的非线性动力响应与可靠性技术相结合,利用四阶矩技术、Edgeworth级数方法对齿轮振动的振幅响应和系统传递误差进行了可靠性分析,并基于失效模式相互独立分析了系统的可靠度.在可靠度分析基础上求解了可靠度对随机参数均值与方差的灵敏度.所述方法可有效地解决齿轮系统的振动可靠性问题,并可指导其结构的优化设计,以减少因振动引起的齿轮系统传动的不稳定性问题.

| Abstract: | Reliability and reliability based sensitivity problem of a gear coupling vibration system was solved with the reliability model established on the basis of the dynamical model of the gear system.Combining the nonlinear dynamical response with the reliability analysis technique,the fourth moment technique and Edgeworth series method are used to calculate the reliability of the vibrating amplitudes and the transmission error.The system reliability is obtained with independence of failure modes.The reliability... |
