Hydroplaning - 2 hour Zoom Training
DATE: Friday, 16 January 2025
TIME: 12 noon - 2pm EST (GMT-5, or 9am-11am Pacific Time)
COST: Free for NAPARS members; $6 for non-members
ACTAR: This event has been submitted for ACTAR CEU consideration.
All attendees will be able to request an attendance certificate during the presentation.
The presentation will be recorded and put in the Reference Library along with any supporting material.
TOPICS TO BE DISCUSSED:
==> Traditional derivation of hydroplaning – aircraft, tire pressure, locked wheel skid
==> Application to road vehicles – tire size, tread depth, surface macrotexture, water film thickness
==> Modern testing of wet tire performance
==> Wet tire characteristics – pneumatic trail and hydrodynamic drag
==> Comparison of hydroplane testing and theory to hydroplane case studies (Daytona, Oscoda, LA)
==> Application of hydroplaning theory in accident reconstruction
OUR SPEAKER:
Alan Moore is one of our favorite guests. He is a mechanical engineer and principal of A.B.Moore Forensic Engineering. (https://www.abmoore.com/home.html)
He specializes in vehicle accident reconstruction, vehicle design analysis, and mechanical engineering consulting.
Mr. Moore holds a Bachelor of Science in Mechanical Engineering from Michigan State University and a Masters degree in Business Administration from the University of Florida. He is a licensed Professional Engineer, a Board Certified Forensic Engineer, and an ACTAR-certified accident reconstructionist. His past experience includes two decades of accident reconstruction and automotive engineering.
He previously worked at Ford Motor Company as a design engineer on the Ford Expedition and Excursion. Mr. Moore also serves as a high-performance driving coach for aspiring race car drivers through the Porsche Club of America.
Some Hydroplaning references to freshen up with before the show:
Start with Frank Navin's SAE paper 950138, "Hydroplaning and Accident Reconstruction", and then "Single Vehicle Wet Road Loss of Control; Effects of Tire Tread Depth and Placement", Blythe & Day, SAE 2002-01-0553, and "Realistic Rear Axle Hydroplaning during Forward Motion" by, Metz, Kinney, and Herling, SAE 2006-01-1560
Then perhaps some of the early work:
Pneumatic Tire Hydroplaning and Some Effects on Vehicle Performance, Horne & Joyner, SAE 650145
Tires & Hydroplaning, Albert, SAE 680140
What makes Pavements Slippery?, Meyer, SAE 710572
Testing and Analysis of Tire Hydroplaning, Yeager & Tuttle, SAE 720471
Then perhaps some of the more recent work:
Braking Force Transfer Capabilities of Tires on Wet Roads, Topp, et al., 2008 EVU
Estimation of Tire-Road Friction Using Tire Vibration Model, Takaji Umeno, et al., SAE 2002-01-1183
