The eta/VPG software application is revolutionary. Integrated at an earlier
stage of the design process, eta/VPG reduces time, reduces costs and improves
quality. eta/VPGs unique analysis approach, not available with any other CAE
product, now allows the automotive industry to achieve its quest of reducing
time-to-market and prototype costs.
This streamlined CAE software package provides an event-based simulation
solution of non-linear dynamic problems. eta/VPGs single software package
overcomes the limitations of existing CAE analysis methods. It is design to
analyze the behavior of mechanical and structural systems, as simple as linkages,
and as complex as full vehicles for vehicle impact, durability and vibration
analysis.
Delivered in 3 independent modules, eta/VPG can be tailored to the needs of
the user, providing a set of tools which improve productivity, increase quality
and yet are affordable.
VPG/PrePost
 Building finite element models can be a tedious, demanding task. VPG/PrePost
provides users an advanced toolset to create complex models, and review the
results of the analysis.
Automeshing
VPG/PrePost includes best-of-class automeshing tools that produce high quality
meshes that meet the demands of todays fast-paced product development schedules.
Automated Weld Generation
By automating much of the tedious modeling work, VPG can increase
productivity while improving the quality of models. Automated generation of
spotwelds accelerates the model creation process by allowing users to select
from a variety of spotweld methods for their model.
Zero Text Editing Environment
All model parameters can be defined inside VPG, eliminating the need for
external text editing operations. VPG/PrePost allows users to define every
possible material, contact or element type available in NASTRAN or LS-DYNA.
VPG/Structure
 VPG/Structure has provided engineers with the ability to study the dynamic
behavior of their mechanical systems like no other analysis tool. Including
component flexibility within the simulation is a natural extension of the VPG
analysis and provides a unique insight for the engineer.
Suspension System Templates
VPG/Structure includes templates which allow the creation of typical automotive
suspensions. Creation of a complex suspension model is as easy as following the process guidance tools. VPG also includes an
interface which allows the engineer to import legacy ADAMS models for an easy
upgrade to a high fidelity VPG simulation.
Tire Modeling
Tire models are the key to a successful, accurate vehicle simulation. VPGs tire
models provide an accurate way to simulate the vehicle and roadway interaction.
Tire models may be generated using several different modeling options within VPG.
Signal Processing and Fatigue Calculation
eta/VPG includes signal processing tools that can be used to study the
dynamic behavior in detail. Using these tools, mode shapes may be reconstructed
and displayed. eta/VPG also includes a fatigue analysis program which can
evaluate the dynamic stress history of the model, and determine the potential of
durability concerns.
VPG/Safety
 VPG/Safety delivers a complete set of automotive impact and safety tools for
FMVSS and ECE requirements. These tools allow engineers to quickly set-up and
execute complex vehicle simulations. VPG/Safety automates much of the model set-up
process, but provides the engineer the flexibility needed to address a variety
of analysis needs.
Process Guidance Tools
Parameterization of the process used to create impact analysis models can result
in productivity and quality improvements for common impact analyses as well as
creating a consistent process for a department or company.
VPG/Safetys Process Guidance approach provides a way to easily specify the
position and boundary conditions for impact analysis tools such as barriers and dummies.
Crash Tool Library
VPGs Crash Tool Library provides the user the tools necessary to perform the
FMVSS or ECE analyses used for vehicle development. Users may customize the
library with their own crash tools or use VPGs barriers and dummies to create simulations such as US or ECE Side Impact, Head Impact or seat
mounting integrity.
