Overview on ANVC Systems and the Future with Smart Embedded Solutions 2015-01-2215
How to decrease noise and vibration exposure has been of interest for many years. Empirical data have indicated that too high dose values can create multiple problems to a human body - often severe. Some years back, the European Machinery Directive has increased the responsibility for manufacturers and employers to make sure limits are complying with legislation. Classical technology often consists of passive solutions aiming at trying to cut back on noise and vibration levels. For low frequency, these methods are often lacking the needed performance especially if weight should be considered at the same time. A smart combination of passive and active techniques can make a real difference. Today, with possibilities for low cost and embedded electronics and the rapid development of new actuators, a vast range of applications are possible for this combined combat approach, with a financial advantage as well. Today, multiple products also utilize embedded “electronic muscles,” able to counteract harmful sound and vibration in real-time - featuring advanced control systems. All this then becomes an invisible function in the vehicle, machine or tool. The launch of such systems and successful acceptance often requires international compliance with applicable standards. New sensor concepts and approaches in combination with consumer and automotive wireless and network solutions are often key ingredients for success. It is impossible to fully grasp how this smart and embedded technology can revolutionize the sound and vibration business and open new business segments. This paper will outline these new markets and applications and give some examples from a number of applications.
