On the one hand it is provided with a strain gauge 6 spread over the surface of the driving shaft 3 and a strain amplifier for amplifying its output, and both of them are connected with wire through a central bore of the driving shaft 3. The intensity of strain of the guide vane 1 outputted by the strain amplifier 7 is inputted so that a calculation circuit 8 as determination means operates to diagnose the occurrence of foreign matter. When a foreign matter hits against the blade 2 of the guide vane 1, and amplitude of strain generated on the driving shaft 3 increases for a certain period of time. At this time, a comparison is made between a measured amplitude of strain of the driving shaft 3 and a threshold value, and as the measured value exceeds the threshold value, the occurrence of foreign matter is determined.

Next, the operation device 13 indicates a turning angle of the gimbal 4 to a gimbal shaft control servo driver 15 after performing operation on a turning angle θof the gimbal 4. Therefore, the servo driver 15 drives a servomotor 6 according to this indication, and can make damping force (fr ) in proportion to the vibration speed (v) of the structure 1 act on the structure 1.

摘要： PURPOSE:To detect phenomena of abnormality, hindrance and failure in a rotary machine in their early stages and to minimize the damage of the machine by a method wherein an area allowed by a normal state of the rotary machine is set in a multi- dimensional space formed by the total amount of state which is expressed by multi- dimensional vectors obtained by unifying conditions of operation and the amounts of phenomena. CONSTITUTION:An operational condition detecting means 31 digitizes conditions of operation such as the number of revolutions and an output and a phenomenon amount detecting means 32 the amounts of phenomena such as shaft vibration resulting from the operation of a rotary machine by A/D conversion means 33 and 34 respectively and output them to an arithmetic means 35. The arithmetic means 35 sets an area allowed by a normal state of the rotary machine in a multi-dimensional space formed by the total amount of state which is expressed as multi-dimensional vectors obtained by integrating the conditions of operation and the amounts of phenomena, and determines the state of operation as sound when the total amount of state obtained by integrating the conditions of operation and the amounts of phenomena inputted is found inside the set normal state, while it determines the state of operation as extraordinary when the total amount of state is found outside the normal state.
