SUMMARY:

We will have Dan Vomhof III (known to many as DV3) with us to show us how to find A & B stiffness coefficients from NHTSA crash test data. 

This presentation will cover the research of data and calculation of Stiffness Coefficients for vehicles based on the NHTSA Crash Tests.

While a presentation of the calculation method will be presented, emphasis will be given to the data points used within the calculations -

• Crush Depths (potentially three  separate sources of depth are available in a given test)
• Crush Width (potentially 2 are available for front and rear tests)
• Crush Energy speed to be used, and how it is calculated
• Weight (Test Weight vs. Curb Weight)
