The defining characteristics of automotive simulation are fast project cadences, numerous load cases, and strong regulatory constraints. Vehicle development is never about meeting a single target—it is about continuously balancing safety, comfort, lightweighting, cost, and manufacturing feasibility.
Industry Characteristics
- Well-established physical testing systems; simulation must align with clearly defined benchmarks
- Platform-based development is prevalent, with different vehicle models sharing a common architecture
- Multiple design iterations demand high model reusability
Typical Tasks
- Safety analysis for frontal, side, rear, and rollover crash scenarios
- Body-in-white modal, stiffness, and dynamic response analysis
- Road noise, wind noise, and transfer path identification
- Durability assessment of spot welds, joints, and local reinforcements
The Case for Co-Simulation
Pursuing crash performance alone typically leads to mass increase and comfort degradation. Focusing exclusively on NVH can compromise structural packaging and manufacturing costs. A more rational approach is to build a multi-objective analysis framework on a unified body model, addressing crash, safety, stiffness, and noise issues in a coordinated manner.
Solution Implementation
From an engineering execution standpoint, it is advisable to establish standardized load-case templates, material card libraries, joint libraries, and correlation benchmarks. This not only improves efficiency on individual projects but also continuously accumulates platform-level R&D assets.
