A Hybrid Model for Vehicle Sideslip Angle Estimation Based on Attention Regression

IEEE Access
Vehicle Active Control Systems (ACS) have been developed to advance driver convenience and safety. These systems require accurate vehicle states such as lateral and longitudinal acceleration, sideslip angle, and yaw rate.

Mitigating surcharge‐induced column‐head cracking in double‐deck shield tunnels using hyperelastic bearing joints

Deep Underground Science and Engineering, EarlyView.
A staged three‐dimensional nonlinear soil–structure interaction (SSI) model is established, in which the initial geostress state, tunnel excavation, lining installation, delayed activation of the internal frame, and subsequent surcharge loading are simulated sequentially.

Calibration of Equivalent Tire Cornering Stiffness for Vehicle Reference Model in ESP Based on Fminsearch Method

Proceedings of the 2nd International Conference on Electronic and Mechanical Engineering and Information Technology (2012), 2012
The 2-DOF vehicle model is generally used to be reference model of automotive electronic stability program (ESP), while the equivalent tire cornering stiffnesses of front and rear axles are key parameters to build it. A 2-DOF vehicle model is built, and a direct searching unconstrained nonlinear optimization method-Fminsearch is introduced for ...

Seismic Response of Existing Masonry‐Infilled RC Frame Structures Retrofitted with Steel Exoskeletons

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Considering the needs for reducing carbon emissions and except for extreme cases of very degraded existing structures, research on technologies allowing continued use or upgrading of older buildings has become a priority topic. Generally, research on upgrading of reinforced concrete frame structures certainly has a prominent role, because of ...

Bending Fatigue Evaluation and Failure Modes of Ultra‐Thin Silicon Chips on Flexible Substrates

FlexTech, EarlyView.
This study investigates the fatigue lifetime of 20‐μm‐thick chips under bending deformation. Three failure modes are identified: metal pad wearing, metal stress migration, and gold wire break. The underlying mechanisms are analyzed through micro‐scale characterization, and temperature effects on fatigue lifetime are explored.

A Model Predictive Controller with Longitudinal Speed Compensation for Autonomous Vehicle Path Tracking

Applied Sciences, 2019
Autonomous vehicle path tracking accuracy faces challenges in being accomplished due to the assumption that the longitudinal speed is constant in the prediction horizon in a model predictive control (MPC) control frame.

Mechanical stability in flexible perovskite solar cells: Interface engineering and device design

FlexMat, EarlyView.
Statistics of the improvement methods for f‐PSCs. Abstract Flexible perovskite solar cells (f‐PSCs) demonstrate significant potential for application in next‐generation wearable electronic devices and photovoltaic building integration due to their high power conversion efficiency and excellent power‐to‐weight ratio. However, the inherent brittleness of

Research on tread modeling of physical characteristics tire model (Translated) (Verification of theoretical validity of TM Tire Model)

Mechanical Engineering Journal
In the early stages of chassis model-based development, we needed a tire physical model that could be handled easily, and we devised the TM Tire Model. Some tire samples have verified that the TM Tire Model is superior to existing physical characteristic

Designing γ‐TiAl Alloys With Refined Twin‐Lamellar Microstructures via Machine Learning‐Driven Phase‐Field Methods

Materials Genome Engineering Advances, EarlyView.
Dual‐phase γ‐TiAl alloys with refined twin‐lamellar (RTL) structures exhibit optimal strength‐ductility synergy. Here, phase‐field simulations reveal composition‐stress‐dependent refined twin‐lamellar (RTL) microstructure evolution. Machine learning (CatBoost + NSGA‐III) trained on phase‐field images predicts optimal RTL‐stress‐composition design space.

Computational Analysis of the Vibrational Response of Lunar Regolith Made of Nonspherical Grains

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Vibration‐based systems have shown that appropriately oriented and tuned mechanical oscillations can disrupt regolith interlocking and promote flow. Building on this evidence, the present study investigates vibration‐controlled granular discharge as a potential ISRU (In Situ Resource Utilization) strategy, with the aim of supporting ...
