Brake Rotor Testing
Resonance Frequencies of Brake Rotors have always been a known contributor to brake noise and premature wear of brake pads and shoes. This presentation discusses: Brake Rotor Modes, Modal Characteristics, Vibration Excitation Methods, FRF 3 Modes of Vibration, Vibration Response Measurements, Brake Rotor Resonance Frequency, Automated Impactors and Contact vs Non-Contact Sensors.

Signalysis was featured in a recent NVH article written by Desktop Engineering Magazine. Here is an excerpt from Neil Coleman:
“The application will typically define the hardware and software requirements for a NVH test. Normally, you cannot mix and match analysis software with data acquisition hardware. However, there are a few companies that do offer cross platform support. Most companies will normally adopt a vendor’s technology based on functionality, channel count, technical capabilities and of course the cost,” says Neil Coleman, president and CEO of Signalysis.
