Active Antivibration Decoupling

Active antivibration systems provide a viable solution to improve this design compromise. Active systems can reduce the transmission of vibrations between two structures while maintaining the high static stiffness required for durability performance.

Active antivibration systems can be supported with pneumatic or electrical actuators. Pneumatic actuators provide lower frequency response and draw their power from the vacuum generated by a gasoline engine, the vacuum pump in diesel vehicles, or use pressures generated by pneumatic suspension pumps.

Electrical actuators provide a higher frequency response and can utilize the electrical energy source available on all vehicles. Their advanced design provides very low energy consumption.

Active antivibration solutions can be accomplished via a single degree of freedom, or it may be preferable to apply a global treatment using one or several active actuators judiciously placed at favorable locations for structure transfer functions. Dynamic forces optimize the vibrational behavior or the acoustic quality of a vehicle.

Paulstra has developed a wide range of active products including electronic control systems and control algorithms. These systems can be controlled in open or closed loop.
