The vehicle description for the coarse model is identical to the detailed model:
| Specification | Detail |
|---|---|
| Vehicle Identification Number (VIN) | JTDBT4K37A4067025 |
| Body Type | Sedan 4-Door |
| Weight | 1,078 kg (2,377 lb) |
| Engine Type | 1.5-liter L4 DOHC 16V |
| Transmission | Manual |
| Tire Size | P185/60R15 |
Model Complexity (Version 1):
| Feature | Count |
|---|---|
| Elements | 378,376 |
| Nodes | 393,165 |

Model Development and Validation
Both the detailed and coarse models were meticulously developed through a reverse engineering process by researchers at the Center for Collision Safety and Analysis, under contract with the Federal Highway Administration. These models are computer representations of a real-world 2010 Toyota Yaris sedan, built for use in LS-DYNA, a nonlinear explicit finite element code widely used in crash simulation.
Rigorous validation procedures were undertaken to ensure the accuracy and reliability of these models. Validation included comparisons against full-scale crash tests, assessments of inertial properties, and suspension response tests. The models have been validated against frontal crash tests and barrier crash tests, confirming their suitability for simulating real-world crash scenarios. They conform to the Manual for Assessing Safety Hardware requirements for a 1100C test vehicle, further attesting to their quality and applicability in safety research.
These 2010 Toyota Yaris finite element models are valuable assets for researchers and engineers working on occupant safety, vehicle compatibility, and barrier system design. The availability of both detailed and coarse versions provides flexibility for various simulation needs and computational capabilities, supporting advancements in automotive safety engineering.
