Fastening elements for vibration and noise decoupling
SITEC® is our answer to the current trend in NVH (noise, vibration, harshness) development. We focus on vibrations produced by actuators such as pumps, compressors and engines.
Our SITEC® elements provide you with intelligent solutions that fasten while also reducing noise and vibrations.
Choose the screw or plug that suits your mounting component from the various SITEC® fastener variants. You can also choose from different materials (e.g. for different temperature requirements).
Whichever SITEC® variant you choose, they are all quick and easy to assemble.
One method for reducing vibrations and the resulting noise emissions is damping. During material-based damping, kinetic vibration energy is converted into thermal energy.
The principle of damping describes the reduction of an output quantity over time. This energy conversion process can be achieved with SITEC® fasteners using technical elastomers.
Another method for reducing noise emissions is vibration isolation. Unlike damping, this does not involve conversion of energy to reduce the amplitude. Instead, the vibrations are detuned.
The principle behind this is that excitation is directly absorbed by an elastic fastener. The spring rate of the fastener is fine-tuned so that energy is transferred at a considerably reduced amplitude. This type of reduction is primarily employed for applications that generate high levels of vibration.
