| 摘 要： | 国内外的学者只对单级行星齿轮传动系统的固有频率参数敏感度进行了研究,而两级人字齿行星传动系统的固有频率参数敏感度研究还未见报导。文中针对大型舰船机械装置中常用的两级人字齿行星齿轮系统,进行了固有频率的参数敏感度分析,主要研究了各啮合刚度的变化对系统固有频率的影响。首先,利用两级人字齿行星传动的振动模态特性,对敏感度的计算公式进行了简化,并建立了敏感度与模态应变能的关系,通过应变能的变化就可以确定各振动模态中固有频率的参数敏感度,从而为减小振动和结构优化设计提供重要的参考。

| Abstract: | The study on natural frequency sensitivities to system parameters of two stage planetary gear train with double helical tooth was not reported,though natural frequency sensitivities of the one stage planetary gear were investigated by some researchers.In this paper,parameters under consideration mainly include mesh stiffnesses.Using the well-defined vibration mode properties of tuned two stage planetary gears,the eigensensitivities are calculated and expressed in simple,exact formulae.These formulae con-nec... |
