In the fourth part, by similitude of diagnosing diseases in medical practice, all available informations together with new measuring technique are collected for "sympton"of crack, with the above information a new branch of mathematics-fuzzy mathematics is utilized to judge whether there is any transverse crack in rotor shaft.

在第四部分中，借鉴医学上对疾病的诊断，总结了借助振动试验采集转子轴系裂纹信息的方法，提出了用电涡流测振仪测量转轴裂纹伩息的新方法。

In chapter 2 it brings total system goals then analyses design of system framework and compartmentalizes system function structure.

第二章首先对本系统的开发物理原型—创意式组合式轴系结构设计实验箱进行了介绍。

Shafting ; crankling vibration ; frequency response function

轴系；弯扭振动；频域响应函数

According to the method, model dimension is contracted to five by the way of selecting the unit in which amount of I/K is m inimal. Then sensitivity of frequency to stiffness is calculated. After the diff erence between measured frequency and calculated frequency have been got, the ad justed amount of stiffness is calculated by the using of the sensitivity and the frequency difference.

该方法按照I/K最小优先合并原则，将轴系模型自由度数缩聚为5，分析该模型4个刚度对前4阶频率的敏感度，算出实测的前4阶频率和模型计算频率之间的差值，利用敏感度和频率差值计算出刚度的调整量。
