Brake Development
Under certain operating conditions, the complex dynamics between the brake caliper, pads, and disk can cause unwanted squealing.
Out-of-plane Vibration
Measurements with a Polytec 3-D Scanning Vibrometer acquire complete vibration vector data showing the spatial dynamics of the brake disk. Using this technology, researchers have managed to track down and control the causes of undesired noises when braking.
Sound Field Visualization
- Brake Sound Field
Scanning vibrometers are used to visualize the sound field emitted from an object.
