subject: Active Vibration Control – Need of the Hour in All Industries [print this page] Active Vibration Control Need of the Hour in All Industries
Active vibration control involves applying opposite and equal force stop the motion in a vibrating machine. It is an important factor, which makes or mars the manufacturing industry sector these days.
Need for vibration control systems:
The reasons for controlling these vibrations may be different in different industry sectors. While in some, it is required for greater performance, in some others it is used to elongate the shelf life of machineries. We can take an example from the semiconductor wafers production industry, where active control systems are used to accomplish the photolithography steps in an essentially vibration-free environment. If this is not done, it might lead to blurring of the features of the sub-micrometer.
How does active vibration control systems work?
Due to their importance in the overall outcome in all industry sectors, users on the robustness of a vibration-controlling device. In addition, this is especially important keeping in view the sensitivity of structural control to modal uncertainties. Most of the users today use simple local and decentralized controllers. Among the various components used in these controllers are a massive platform suspended with active drivers, accelerometers, electronic amplifier system and pneumatic or hydraulic components (for large systems).
Active vibration control systems application areas:
Almost all industry sectors use these systems to control or reduce vibrations, though the degree of usage differs in various situations. It is to be mentioned here this is not a new concept, as it has been in use in various manufacturing industries since long. However, nowadays, these systems are commercially available with the best of features. Here we can take the example of vibration control systems used in reducing vibration in helicopters, which is useful in offering better comfort. The advantage of these systems is that they weight less than traditional passive technologies. The vibration control systems are used in both smaller and larger structures and machines. You can use them for chatter control in machine tools (e.g. grinding, milling machines), in active damping of truss structures, active tendon control of bridges and even vibro-acoustic control of steel railways bridges.
Use any of the active vibration control systems that are suitable for your application area. For more details, you can research online to get the very best from them.
