Optimization Design for Detonation Powerplant Based on LS-DYNA Simulation

Dynamics Analysis on Roadheader Cutting Head Based on LS-DYNA

The dynamic performances of head cutter for boom-type excavator were researched, and the corresponding dynamic equilibrium equations were derived. Based on the explicit dynamics analysis techniques of the Software ANSYS/LS-DYNA, transient dynamic analysis was carried out to simulate the cutting process of head cutter, and the main kinetic parameters were achieved. Finally, the cutting performan...

LS-DYNA® Best-Practices: Networking, MPI and Parallel File System Effect on LS-DYNA Performance

From concept to engineering, and from design to test and manufacturing, the automotive industry relies on powerful virtual development solutions. CFD and crash simulations are performed in an effort to secure quality and accelerate the development process. The recent trends in cluster environments, such as multi-core CPUs, GPUs, cluster file systems and new interconnect speeds and offloading ca...

Performance of the Hybrid LS-DYNA on Crash Simulation with the Multicore Architecture

Using crash simulation models, we investigate the multicore performance of the newly developed hybrid LS-DYNA, a method whose speedup arises from both shared-memory and message-passing parallelisms. Theoretically, the hybrid method gains performance advantages over the traditional, message-passing-parallel (MPP) LS-DYNA for two reasons. First, the addition of shared-memory parallelism to the me...

Development of Guidelines for Deformable and Rigid Switch in Ls-dyna Simulation

Pre-processor Software for Calibration of LS-DYNA Material Models

LS-DYNA contains a wealth of material models that allow for the simulation of transient phenomena. These models are often quite complex and difficult to calibrate. We present CAE Modeler, a generalized pre-processor software used to convert material property data into material parameters for different material models used in CAE. In this paper, CAE Modeler is used to streamline the conversion o...
