Numerical Verification of the Drive-By Monitoring Method for Identifying Vehicle and Bridge Mechanical Parameters

Autor: Kyosuke Yamamoto, Ryota Shin, Eugene Mudahemuka

Publikováno v: Applied Sciences, Vol 13, Iss 5, p 3049 (2023)

The PRE (numerical simulation-based vehicle and bridge parameter and road roughness estimation) method uses vehicle vibration data to identify the vehicle’s and bridge’s mechanical parameters and estimate road unevenness simultaneously. This meth
