Slip misdetection phenomena caused by bogie vibration during re-adhesion control of railway vehicle
Nihon Kikai Gakkai ronbunshu, 2021 Wheel slips in railway vehicles cause poor acceleration and damage to wheels and rails. Re-adhesion control is widely used to resolve wheel slips in electric motor cars.

DETERMINATION OF LINEAR AND NONLINEAR ROLL DAMPING COEFFICIENTS OF A SHIP SECTION USING CFD [PDF]
Brodogradnja : An International Journal of Naval Architecture and Ocean Engineering for Research and Development, 2019 The most prevalently used method to obtain the nonlinear roll damping coefficient is the free roll decay test. However, this method can only be conducted at the resonance frequency and thus cannot consider the effect of the frequency. This is a certain limitation as the resonance frequency can be changed at any time by the ship’s loading conditions ...

Estimation of Roll Damping Coefficient from Roll and Trajectory Data Using Extended Kalman Filter [PDF]
, 2020 Abstract In this paper, a new method to estimate roll aerodynamic characteristics of a rolling projectiles is proposed. It is estimated from the measured roll rate and trajectory positional data using Extended Kalman Filter. Modified point mass model of trajectory modelling, in state space form, is used to represent system dynamics of Extended ...
