This model is the computer representation of a 2018 Dodge Ram pick-up truck for use in crash simulations. The model was developed through reverse engineering by the CCSA under a contract with the Federal Highway Administration. CCSA performed a comprehensive vehicle tear down for engineering analysis that included manufacturing technology assessment, material utilization, and complete vehicle geometry scanning. The geometry and material test data from the baseline vehicle tear down was used to build detailed finite element analysis (FEA) simulation models suitable for crashworthiness using LS-DYNA.
The model was validated against several full-scale crash tests. It is expected to support current and future research related to occupant risk and vehicle compatibility, as well as barrier crash evaluation, research, and development efforts. The model confirms to the Manual for Assessing Safety Hardware requirements for a 2270P test vehicle.
Initial verification and validation of the model included completeness checks, comparisons of actual and model inertial properties, suspension response tests, and comparisons to actual frontal crash test data. Subsequent efforts compared simulation results to other available crash tests.
The resulting detailed finite element vehicle model has about 2.7 million elements. It includes details of the structural and drivetrain components. The model was constructed to include full functional capabilities of the suspension and steering subsystems allowing for non-level terrain analyses.
Average element size of the model is 6–8 mm with a minimum size of 5 mm. Typical simulation time step is 1.0 µs. The model was created for use with the LS-DYNA nonlinear explicit finite element code. Approximate computation time to run a 200 ms simulation using 16 cores is .
