摘要： A method for detecting defects in a rotational element of a machine based on changes in measured vibration energy includes: (a) collecting vibration data over an extended period of time using vibration sensors attached to the machine; (b) processing the vibration data to generate a time waveform comprising processed vibration values sampled during sequential sampling time intervals within the extended period of time; (c) detecting multiple time blocks within the extended period of time during which the processed vibration values exhibit sustained increases at progressively increasing rates; and (d) generating alerts based on detection of the multiple time blocks during which the processed vibration values exhibit sustained increases at progressively increasing rates. The multiple time blocks may include a first time block during which the processed vibration values increase at a first rate, and a second time block occurring after the first time block during which the processed vibration values increase at a second rate that is greater than the first rate.

摘要： A computer-executable ratiometric analysis method determines integer components of a rational number ratio or a close approximation of an irrational number ratio. In one embodiment the method uses a ratio of rotational speeds of two rotating assets in a machine or process, generates a new rational number based on the ratio of speeds, and calculates the integer components of the new rational number. The result is the integer ratio relationship between the initial two rational numbers. The method may be used in machinery analysis applications to determine whether a low-order integer ratio relationship exists between two machinery rotating components. Low-order integer ratio relationships in machinery are generally harmful in related machinery rotating components, and detection of such relationships is an important tool in preventing damage to machinery components. In a more general embodiment the algorithm can be used to determine the closest integer roots of any fractional number where this information would be of interest to an analyst in understanding the fractional number.

摘要翻译：计算机可执行的比率分析方法确定有理数比的整数分量或无理数比的近似。在一个实施例中，该方法使用机器或过程中的两个旋转资产的转速比，基于速度比产生新的有理数，并计算新的有理数的整数分量。结果是初始两个有理数之间的整数比关系。该方法可用于机械分析应用中以确定两个机械旋转部件之间是否存在低阶整数比关系。机械中的低阶整数比关系在相关机械旋转部件中通常是有害的，并且检测这种关系是防止机械部件损坏的重要工具。在更一般的实施例中，该算法可以用于确定任何分数的最接近的整数根，其中该信息将在分析人员理解分数中感兴趣。
