McHenry Forum - Crash Reconstruction & Simulation

Realized we hadn't moved The Astro-Spiral Jump Patent from old website to the new website so adding it here for now. For those of you who wonder how it was done and/or want to give it a try, here's how: Spiral Patent cover page.png Raymond .R. McHenry, “Spiral Jump Apparatus”, US Patent No. 3,814,02...

Joining Forces on Distracted Driving The blog was co-authored by: Bruce Landsberg , Vice-Chairman, National Transportation Safety Board Lorraine Martin , President & CEO, National Safety Council Which begins... By now, we all should be aware of the deadly consequences of distracted driving . Ye...

Just for fun in response to the Flat Spin 360 Kia K5 Stunt we thought it might be interesting to simulate the real test To quickly create a Simulation of Reality in the event The Universe IS a Simulation! :-) (OK, that's a joke!) For some additional understanding about the stunt Note we have previou...

Did a quick simulation of a Flat Spin 360 Stunt with msmac3D using a similar vehicle, a little different steer to insure easy 360, and voila! For the video and details on how we set it up please see msmac3D simulation video of Flat Spin 360 Kia K5 Stunt [/size] Flat 360 SImulation SEQ 800x600.png

This is a continuation of my post above on the Flat Spin 360 Stunt Kia K5 Stunt! I Kinda Sorta Figured it out!! Well at least realized an how it could have been easily** done: Use simple launch analysis like the Simple Launch Trajectory calculation below With a range of speeds and ramp angles determ...

Information on the stunt driver for the stunt: Kia stunt driver.jpg Another stunt was performed as part of the KIA K5 promo with his daughter! They're a father/daughter stunt team...fantastic! Aug 2021: Just saw this video of the making of the stunt https://www.youtube.com/watch?v=vUAp6Er4_hM For ad...

on another forum a few other citations recently cited Crush Energy Considerations in Override/Underride Impacts SAE 2002-01-0556 ABSTRACT: In automobile accident reconstruction it is often necessary to quantify the energy dissipated through plastic deformation of vehicle structures. For collisions i...

Taking another look found a little drop ramp section. Might need to investigate and simulate with msmac3D just for fun and to see the reasons for the ramp! We expect it is to provide a lift to insure it doesn't pitch downward to hit the landing ramp Flat 360 Drop Ramp.jpg Here's the stunt again foll...

Just came across this stunt! Great Stunt! Flat spin 360 seq.jpg Will add more information on stunt team/stunt driver and what tools they used to help them set up the stunt. Dec 3rd:Solved! See below for how we think they could have easily designed the stunt! Great Stunt! https://www.youtube.com/watc...
