Background

Vibration is one of the most pervasive problems in engineering industry. Time dependent motion related to vibrations is not only a cause for fatigue failures but also lead to undesirable deflection of structures. The latter is of high concern for many machine tools as it directly affects the quality of the output of the machine. In addition, in many situations, excessive vibrations also lead to noise problem in work area. Hence, a good understanding of the phenomenon – its characteristics and means of its control, is essential.

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) is organizing a 2 day programme on “Noise, Vibration and Harshness consideration in design and Maintenance”

Key Takeaways

After undergoing the programme, the participants will be able to -

• Identify potential sources of vibration and noise in machinery
• Utilise testing and analysis resources for isolating the source of problem
• Use different controlling techniques, based on the characteristics of the vibration problem and noise, to control it
• Understand the testing methodology and how to utilise it for solving problem involving vibration and noise
