【摘要】

：

针对无转速计的瞬时转速估计(IFE)问题,基于Viterbi 算法提出了一种改进型瞬时频率估计方法,并将其应用于变转速工况下滚动轴承的瞬时转速估计.首先,将隐马尔科夫模型中的Viterbi 算法引入转频估计,分析了某一时频平面中代价函数的计算次数;然后,根据欧几里得距离函数的性质,提出了代价函数迭代循环停止的新型判定准则.

拟哈密顿系统首次穿越破坏的数值求解方法

首次穿越是随机动力学研究中的一个难点问题.对在随机激励作用下的工程结构系统而言,描述其运动的状态量如能量、位移等物理量在某个时刻首次超过了安全域,就代表着系统发生了破坏,这就是首次穿越的含义,而系统停留在安全域的概率就是其可靠度.
