摘要：
A method for measuring a tangential tightness of a stator coil within an armature slot of a stator assembly in an electric generator. The stator coil is excited to produce a vibratory response therein. The vibratory response of the stator coil is detected and a frequency response function of the vibratory response is determined. A tangential tightness of the stator coil within the armature slot is estimated based on the frequency response function of the vibratory response of the stator coil.
