Table 1 shows the top 20 best-selling vehicles for 2015, their sales volumes, plus summary results from analyzing an applicable SINCAP test for a proximate Model Year.
For the Silverado and Ram pickups in Table 1, eight SINCAP tests were conducted.
Similar behavior was found in several of the SINCAP tests of Ford F-150 pickups.
Some stiffness variability could be attributable to differences in the engagement of hard points such as pillars and wheels, although the SINCAP test protocol tends to minimize such effects.
The desire to perform SINCAP tests on the widest possible range of vehicles within a finite budget constrains such efforts.
Recommendations for using the present methodology for characterizing vehicle side structures from SINCAP test data are as follows:
