摘要:
本文将Miner关于疲劳破坏的线性累积损伤假说推广到多自由度结构中去, 从而得到了预报多自由度结构持久寿命的简单方法. 文中假定结构是线性的, 且具有小阻尼, 其固有须率之间有足够的间隔. 文中论证了构件损伤率的期望值等于该构件在各个模态中损伤率期望值的和.
Abstract:
This paper applies Miner’s hypothesis of linear cumulative damage of fatigue destruction to multi-degree-of-freedom structures, and arrives at a simple method for predicting the service life of a multi-degree-of-freedom structure (assuming the structure to be linear, with small damping and sufficient separations between its characteristic frequencies).
The expectation of a structure’s damage-rate is proved here to be equal to the sum total of the damage-rate expectations of its various modes.
