Vibration & Noise Analysis  ]
Analysis of vibration and noise is carried out for 'environmental performance evaluation' in order to detect abnormalities or faults
of facilities or to minimize impact on human body in terms of environment. Vibration and noise generated from rotating machines and
parts have their size and frequency, and they can be analyzed precisely to understand abnormal conditions and diagnosis process of
faults without maintenance or disassembly. In addition, it finds a specific frequency that affects the human body and blocks or
eliminates it, so that humans can live a more pleasant and safe life. Therefore, countermeasure against facility fault can be prepared
through vibration and noise analysis in advance and the optimal design for sound-proofing and vibration-proofing cna be possible.
|  Purpose of vibration measurement and evaluation
· Prediction of facility faults is possible! Suitable countermeasures can be established!
Through vibration measurement and evaluation, you can quantitatively and quantitatively analyze the status of the equipment to identify
the cause of the abnormality or defects, and predict future faults, so that appropriate measures can be established.

· Improvement of company's profitability through cost reduction
By efficiently maintaining and managing facilities, it is possible to prevent accidents caused by facility faults and the resulting loss of
human and material. In addition, if equipment failures are reduced, the utilization rate of facilities gets improved, which improves the
productivity of factories and profitability of enterprises. Vibration measurements and evaluations must be conducted in accordance with
the equipment for precision vibration measurement and analysis and professional diagnostic procedures and specification, so the
equipment diagnosis with long experience and expertise and measurement and evaluation by experts are required.

Futuremain has been able to keep the customer's facilities at the optimum condition based on the diagnosis experience of more than 30
years and suggests appropriate countermeasures promptly when faults is found in facilities to reduce the customer's loss.

|  Vibration analysis method of Futuremain
· Analysis of axis tension Rotary shafts used to transmit power from machines to steam turbines, generators, and other rotating machines are subject to unstable operation due to tensional vibrations or whip vibration when excessive load is applied or the rotational speed fluctuates excessively or within a short time. Also, in the case of a drive motor of a crane that frequently operates in normal or reverse operation, torsional vibration due to excessive load may cause shaft cracking and damage the rotating shaft. Therefore, it is essential to review the natural frequency of torsion along with the bending natural frequency when designing the rotary axis.
· Analysis of electric characteristics of electric motor The motor has high efficiency and scarcely breaks down, so it is most used as driving source in industrial plant. However, motor is the equipment which creates electrical energy and it is very difficult to accurately detect the malfunction of the motor due to the simultaneous occurrence of electrical faults and mechanical faults. Generally, vibration analysis method is used to detect faults in motors, but it is very insufficient to detect electromagnetic faults such as dielectric breakdown and magnetic field unbalance. Futuremain is a motor fault detection method that compensates for it. It can diagnose motor precisely by performing diagnostic method considering only electrical characteristics.
· Analysis of structural vibration ODS analysis method which helps to visually observe the movement of the equipment based on the measured values of various position and vibrations in the running facility and Modal analysis method which helps to visually observe the movement at the natural vibration frequency of the equipment by giving external excitation force is performed to implement structural vibration analysis of the facility.
· Analysis of pipe stress In the steam turbine system using high-temperature and high-pressure steam, if the defects are repeatedly generated, excessive stress of the pipe due to the steam pressure is generated. In this case, the problem can be solved through the analysis of the expansion allowable range of each pipe and the stress analysis which acts on pipe. Futuremain carries out stability evaluations according to internationally accepted standards and designs supports for vibration or stress reduction.
· Precise calibration of facilities in Futuremain Appropriate calibration and repairs must be carried out before an unstable state of the plant results in a failure of the plant, which can lead to prevent accidents or reduce the losses caused by the full replacement of the plant. Futuremain can implement the structural change along the calibration of the rotary axis and perform the rotary axis calibration using precision axis alignment and field balancing.
