Automobile plane-motion model including roll motion: Second report (Taking into consideration phase difference of cornering forces between front and rear wheels)

Nihon Kikai Gakkai ronbunshu, 2016
The roll motion of the vehicle has an effect on the yaw natural frequency. Because the yaw natural frequency formula considering this effect is the solution to a quartic equation, the expression of the formula is thought to be complex and ...

Influence of α Lamella Width on Hydrogen Embrittlement Behavior of Ti-6Al-4V Titanium Alloy

Metals
Titanium alloys are susceptible to hydrogen embrittlement (HE) failure when exposed to hydrogen-containing environments, and their microstructural characteristics significantly govern the HE susceptibility.

ANALYSIS OF TRANSVERSE STABILITY PARAMETERS OF HYBRID BUSES WITH ACTIVE TRAILERS [PDF]

Scientific Journal of Silesian University of Technology. Series Transport, 2018
The objective of the article is to determine the transverse stability indexes of hinge-connected buses (HCBs) by applying the computation-analytical method. The transverse stability parameters of hybrid buses with active trailers are analysed.

Ultrasonic roll bite measurements in cold rolling – Roll stress and deformation [PDF]

Journal of Materials Processing Technology, 2017
In cold rolling of thin metal strip, contact conditions between the work rolls and the strip are of great importance: roll deformations and their effect on strip thickness variation may lead to strip flatness defects and thickness inhomogeneity. To control the process, several online measurements are usually carried out such as the rolling load ...

Estimation of Wave Period from Pitch and Roll of a Lidar Buoy

Sensors, 2021
This work proposes a new wave-period estimation (L-dB) method based on the power-spectral-density (PSD) estimation of pitch and roll motional time series of a Doppler wind lidar buoy under the assumption of small angles (±22 deg) and slow yaw drifts (1 ...
