PURPOSE: To provide the vibration-amplitude control method of a mechanical vibration system, which is effective for the analysis of the broad analysis frequency range of the mechanical vibration system and the broad response amplitude characteristic of the mechanical vibration system, and the apparatus using this method. ;CONSTITUTION: A shaker 7 imparts forced vibration to a machine 9 under test. A sensor 10 detects the vibrating state of the machine 9. A vibration-amplitude detecting function 12 analyzes the measured value detected by the sensor 10. These parts are provided. Control is performed based on the specified conditions in correspondence with the phase of a vibrating wave so that the measured value measured with the specified sensor 10 satisfies the specified conditions. At this time, it is preferable that the timing at which the vibration-amplitude function 12 is performed and the function processing of a deviation amplifying function 5, which compares and operates the vibrating-amplitude command value of the vibration-response characteristic tester of the mechanical vibration system and the output signal of the vibration- amplitude detecting function 12 are controlled in correspondence with the phase of the vibrating wave of the vibration-response characteristic tester.;COPYRIGHT: (C)1995,JPO
