Design of a Tracking Controller Based on Machine Learning

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Tracking control of multibody systems is a challenging task requiring detailed modeling and control expertise. Especially in the case of closed‐loop mechanisms, inverse kinematics as part of the controller may become a game stopper due to the extensive calculations required for solving nonlinear equations and inverting complicated functions ...

SCT‐BEM for Transient Heat Conduction and Wave Propagation in 2D Thin‐Walled Structures

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Traditional boundary element method (BEM) faces significant challenges in addressing dynamic problems in thin‐walled structures. These challenges arise primarily from the complexities of handling time‐dependent terms and nearly singular integrals in structures with thin‐shapes.

Application of Surrogate Modeling in Stochastic Analysis of an Ogee Spillway Structure

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT This study investigates the hydraulic performance of an Ogee spillway under varying flow rate conditions, gate opening heights, and spillway widths. Numerical simulations using Flow‐3D, incorporating the (k‐ε) turbulence model and Large Eddy Simulation (LES), were employed alongside surrogate models using MATLAB codes and LP‐TAU to predict ...

Uncertainty Quantification for Nonlinear Vibration of Supercritical Drive Shaft With a Dry Friction Damper

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The supercritical drive shaft is becoming increasingly popular in helicopter transmission system. Dry friction dampers are specially employed to ensure the supercritical shafts crossing the critical speed safely. Due to design tolerances, manufacturing errors and time‐varying factors, the parameters of the damper are inherently uncertain ...

Numerical Modelling of Frictional Sliding Induced Damage and Heating Effects on Rock With an Application to Sievers’ J‐Miniature Drilling on Granite

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT The present study develops a finite element‐based numerical method for simulation of frictional rotational sliding induced damage and heating effects on rock. The method is applied to the Sievers’ J‐ miniature drill test, which is widely used for estimating the rock drillability and predicting the cutter life.

Exploring the Elastic Properties of Interfacial Transition Zone in Concrete Materials Using an Ensemble Learning Approach

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Concrete materials consist of multiple phases with distinct mechanical properties, making it essential to accurately identify the mechanical behavior of both constituent phases and their interfaces for effective multiscale modeling. This study estimates the elastic properties of the interfacial transition zone using a machine learning (ML ...

Drinfel’d double of bialgebroids for string and M theories: dual calculus framework

Journal of High Energy Physics
We extend the notion of Lie bialgebroids for more general bracket structures used in string and M theories. We formalize the notions of calculus and dual calculi on algebroids.
