In this final blog of our Adams-EDEM co-simulation series, Darren Simoni from DSIM Technologies explains how EDEM and Adams have been used during the design of a skid-steer loader to increase the accuracy of system level simulation using less time and effort than traditional load estimation methods.
While additive manufacturing of reinforced polymers is appealing and increasingly considered for production of actual parts, major obstacles must be overcome by engineers. Dimensional accuracy of the part must obey to strict tolerances that may not be met due to thermally induced part distortion or poor surface roughness. On the material side, an anisotropic material behavior is brought in by the specific 3D printed layered architecture and oriented reinforcements. This process-induced material behavior make the part mechanical response challenging to predict.
Therefore, Digimat, the material modeling platform, can offer you a solution to overcome your challenges.
Today's vehicle and powertrain engineers face increasing challenges to meet fuel economy and drive quality targets, while at the same time keep vehicle cost reasonable. Many of the new engine technologies designed to improve fuel economy create difficulties for the noise, vibration, and harshness (NVH) engineer, whose job it is to assure a certain level of comfort for the occupants.
Omni-Lite Industries is an advanced material company. They recently designed a new part that was exhibiting a unique material flow. The part was cold formed out of 1100 aluminum material.
The initial tool design was completed and reviewed using the Simufact.forming simulation. Upon initial review, everything seemed to be acceptable, with the exception of the volume of material in the flange of the part. The second station trap extrusion die radius was then reduced in order to accommodate the material volume requirements.
