Analysis of a Dirt Track Sprint Car Accident
The purposes of the investigation were (a) to attempt to characterize the dynamics of the vehicle motion through videographic analysis, (b) to estimate the accelerative loadings to which the driver would be exposed, (c) to develop a first order analysis model for car and suspension motions which ensue following interlocking of counterrotating wheels, and (d) to determine whether current restraint technology is acceptably strong enough to face such accidents. To begin, a short introductory section characterizing dirt-track midget car racing in general is presented. ...Dirt-track racing presents a very high potential for rollover accidents whenever a sprint car is presented sideways to its direction of travel. A short description of the accident event is presented next, followed by a discussion of the mechanism of tripped and untripped rollover. ...A short description of the accident event is presented next, followed by a discussion of the mechanism of tripped and untripped rollover.
