【摘要】

：

工业生产实践中,常常测得超声波在构件内的传播、振动特性参数值以反演超声波传播速度、构件尺寸及构件内裂纹大小等物理参数.对超声波在构件内的传播、振动特性进行研究有利于提高上述物理参数计算结果的准确度.本文在考虑泊松比或横向变形的条件下对激光超声纵波在杆内的传播、振动特性进行了研究.

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.

一种基于滚动轴承振动信号的瞬时转速估计算法

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.
