Roughness-induced vehicle energy dissipation from crowdsourced smartphone measurements through random vibration theory

Roughness-induced vehicle energy dissipation from crowdsourced smartphone measurements through random vibration theory

We propose, calibrate, and validate a crowdsourced approach for estimating power spectral density (PSD) of road roughness based on an inverse analysis of vertical acceleration measured by a smartphone mounted in an unknown position in a vehicle. Built upon random vibration analysis of a half-car mec...
