Road noise engineering: a state-of-the-art methodology for characterizing tires and suspensions

Eric Sorber, business development automotive NVH testing at Siemens Digital Industries Software, presents a new component characterization technique for better road noise engineering measurements

What is the basis for Siemens’ new methodology for characterizing tires and suspensions?
Our methodology provides direct answers to three well-known automotive industry trends: electrification, diversification and digitalization. The basic premise is this: first, every component of a vehicle is characterized independently using abstract descriptive data such as blocked forces spectra or impedance transfer functions at the connection interfaces.
