I ran simulations with the 2270P vehicle on the F-shape PCB at 25 degrees and speeds of 225 and 30 mph.

 

  1. For 25 mph impact speed, the dynamic deflection was 18.375” and the working width was 40.875”
  2. For 30 mph impact speed, the dynamic deflection was 26.25” and the working width was 48.75”

 

Thanks
