Tech Sessions

Details
Category: Library

The EDC Tech Session series is published for the benefit of HVE, HVE-2D, and HVE-CSI users, as well as professionals in the fields of vehicle dynamics and accident reconstruction. Its purpose is to explore the engineering foundations behind simulation—bridging theory, application, and interpretation.

Each session focuses on a specific technical or analytical topic, explaining how the underlying physics and computational methods relate to real-world vehicle behavior and reconstruction practice. Topics may include:

  • Simulation theory and modeling fundamentals

  • Practical examples of HVE calculations and outputs

  • Broader discussions on simulation methodology

  • Tips for interpreting and validating results against physical evidence

  • References to SAE standards and established analytical methods

The Tech Session series is designed to enhance users’ understanding of vehicle simulation—whether using HVE or other analytical tools—by connecting mathematical models to the engineering judgment required for accurate and defensible results.

HVE Accelerometer Output

This Tech Session explains how HVE’s Accelerometer Output computes
the position, velocity, and acceleration of a point rigidly attached to the
vehicle body such as an accelerometer or any sensor mounted away from
the vehicle’s center of gravity (CG). By combining translational and
rotational motion, it determines the motion an accelerometer
experiences anywhere on the vehicle at any instant in the simulation.
