Mass dampers are ideal for applications where vibrations transmitted from the road surface or the engine into the chassis need to be reduced with opposing inertial forces. Using mass dampers, Vibracoustic adapts the absorber to the available package mainly by changing the contours of the inertia mass.

The outer shape of the mass damper is highly flexible, as the inertia mass does not need to be inserted into a vulcanization mold. Its geometry can be precisely designed to achieve the specific vibration modes and no unnecessary weight is used. The optimized rubber compound around the joint significantly reduces noise and vibration.

To balance out vibrations with opposing inertial forces, an additional spring-mass system with the same frequency, but opposite amplitude, acts on the vibrating structure.

Linear dampers are a strategic design element to counteract unwanted noise and vibrations – especially in lightweight structures.

Mass dampers are ideal for use in applications where vibrations need to be balanced with opposing inertial forces. In these configurations, an additional spring-mass system with the same frequency, but opposite amplitude, acts on the vibrating structure, effectively eliminating its vibrations. The way mass dampers work means they can be used in a wide variety of scenarios: transmissions, steering wheels, and even whole convertibles are just some of the applications that make use of this indispensable system to prevent Noise, Vibration and Harshness issues.

Active mass dampers are another way of improving comfort even further. They use a sensor placed on the vibrating structure and an ECU (Electric Control Unit) that controls a solenoid which is able to accelerate the absorber mass. This way, active mass dampers not only come with a design that weighs less and takes up less space than their conventional counterparts, but they are also able to adjust to variables such as additional cargo load, road surface excitation, and temperature.
