This paper describes a multiagent variant of Dyna-Q called M-Dyna-Q. Dyna-Q is an integrated single-agent framework for planning, reacting, and learning. Like DynaQ, M-Dyna-Q employs two key ideas: learning results can serve as a valuable input for both planning and reacting, and results of planning and reacting can serve as a valuable input to learning. M-Dyna-Q extends Dyna-Q in that planning...

In this paper, the design and development of the Delphi Driver Protection Module (DDPM) using a systems and virtual engineering approach is presented. LS-DYNA software tool was used in virtual prototype studies. The DDPM consists of driver side energy absorbing components. The components included in this module are 1) an adaptive Energy Absorbing (EA) steering column, 2) driver air bag, 3) stee...

The present work will introduce some of the resent developments in the Incompressible CFD (ICFD) solver currently under development in LS-DYNA. The main feature of this solver is its ability to couple with any solid model to perform Fluid-Structure interaction (FSI) analysis. Highly non-linear behavior is supported by using automatic re-meshing strategies to maintain element quality within acce...

At present, aluminum bumper has been used in the field of passenger cars. In order to provide technical reference for alloy be developed, and better develop bumper, this project analyzes material process an existing from perspective mechanical properties, composition, connection method between each component. Through crushing, static pressure, collision test simulation technology, performance b...

Abstract The dynamic contact parameters such as force, stress and rotational speed fluctuate with time during the actual operation of a sprag clutch. To this end, ANSYS LS-DYNA is applied to simulate dynamics various types clutches different wedge surfaces obtain curves speed, windup angle each component time. wedging performance all-phase type PCE (positive continuous engagement) clutch compar...

Robust finite element models are utilised for their ability to predict simple complex mechanical behaviour under certain conditions at a very low cost compared experimental studies, as this reduces the need physical prototypes while allowing optimisation of components. In paper, various parameters in techniques were reviewed simulate crushing glass/epoxy tubes with different material models, me...

assessing the behavior of composite structures which are subjected to impact loads is one of the important subjects in the field of mechanical sciences. using thin-walled tubes which collapsed and absorbed the impact energy is a well-known method to prevent damages to the other parts of the structures. in this paper, deformations, crushing length, peak load, mean force and energy absorption cap...
