VPG\’s Structure module allows the user to define LS-DYNA models which can be used for mechanical system analysis including tire model, suspension model and road surfaces. eta/VPG uses an analysis approach consistent with test environments dynamic non-linear analysis using real-time boundary conditions.
Road Surface Models
* Digitized from MGA proving ground roads
* Any 3-D data can be used to generate road surfaces
Tire Models
* 3-D FEA models including the tire air pressure
* Frictional Contact interface with road
* Validated versus test data
Vehicle Dynamics
* Road Load Generation
* Use of simplified models for event-based loads
* Rigid and flexible members
* Component or sub-system studies
Full System & Component Durability / Fatigue Assessment
* Time-domain transient stress and strain prediction
* eta/VPG fatigue analysis tool included
* Allows multiple material assignment
* Provides a way to create user defined materials
* Users can output files useful in other fatigue codes
* Simulation of durability critical proving ground events
* Calculate material damage of each event
* Calculate the “occurrence” cycles
* Accumulate damages per cycle to predict fatigue life.
