2024 International LS-DYNA Conference, Metro Detroit, Michigan, USA - Radha Krishnan, Sridhar Bijjala, Rajasekaran Mohan (Detroit Engineered Products)
Abstract
Crashworthiness analysis is a cornerstone of automotive safety design, requiring precise simulation of vehicle impacts to ensure passenger safety. Traditional finite element models used for crash simulations are computationally intensive, often leading to longer design cycles.
DEP MeshWorks introduces a groundbreaking solution: Parametric Reduced Order Modeling (ROM). This innovative technology simplifies the complexity of crash models, significantly reducing analysis times while maintaining high accuracy. Engineers can now optimize crash performance faster and more efficiently, paving the way for safer vehicles and shorter development timelines.
Introducing Parametric Reduced Order Modeling (ROM)
DEP MeshWorks' Parametric ROM technology leverages advanced algorithms to convert detailed finite element models into reduced-order representations. These ROMs maintain 85-95% correlation accuracy with the original models, enabling engineers to conduct faster simulations without sacrificing precision.
Key Features of ROM Technology:
- Mass and Inertia Representation: Captures the dynamic response of critical structures.
- Stiffness and Damping Parameters: Ensures reliable behavior under crash conditions.
- Ease of Use: Simplified interface within DEP MeshWorks, reducing learning curves for engineers.
By integrating ROM into crash simulations, engineers can analyze a wide range of parameters, including sectional forces, velocity, acceleration, and intrusion values, in half the time required by traditional methods.
