AITools WinCRASH Module

ARSoftware™ for Windows™ is pleased to announce WinCRASH, formerly known as  SLAM for Windows™. WinCRASH has been developed as micro computer assistance for the knowledgeable reconstructionist. It cannot replace the experience and training of the analyst, however, it is a powerful aid to analysis as it frees time from tedious calculation and allows the user to test many more assumptions than would be possible by hand or by calculator. See AITools WinCRASH Sample Screens.

WinCRASH is based on the work sponsored by NHTSA in the development of the CRASH3 computer program. Like CRASH3, WinCRASH can also compute speed change from damage profiles and calculate linear momentum solutions based on impact and rest positions.

WinCRASH uses the standard sign conventions and symbols established by NHTSA. For the new user, the program and comprehensive user's manual will open the door to the power of computer aided reconstruction.

An important concept used in collision analysis is DELTA-V or COLLISION SPEED CHANGE during the impact phase. Not only is this concept important for an understanding of vehicle dynamics during collision, but it is an indispensable parameter for the determination of occupant dynamics and injury potential.

WinCRASH provides a capability that generates screen and printer MOMENTUM DIAGRAMS for both the CRUSH DERIVED SPEED CHANGE and the LINEAR MOMENTUM SPEED CHANGE. Consistency between the solutions will be graphically apparent.

The user can also see graphic screen displays of the input data immediately upon entry as a visual check of the signs and magnitudes.

FEATURES

• Emphasis on user friendly data entry and results display.
• Advanced damage profiles with up to twelve measurements at user defined intervals.
• Ability to move the collision force location to suit the specific structure of the vehicles or to ensure that the force is located within the direct contact area of the crush zone.
• Built in data base for crush A&B coefficients and car measurements.
• Residual velocity specification to allow for multiple collisions.
• Improved handling of parallel velocity calculations. Head-on collision linear momentum solution is easily calculated when one vehicle speed can be specified.
• Proper common velocity check option.
• Ability to save intermediate results at any time.
• Technical manual contains the derivations of the formulas used by the program to enable the reconstructionist to calculate the same results by hand to prove the results for court.
• Built-in error analysis.
• Custom reports can be printed with or without confidence levels.
• Training available through IPTM.

TRAINING

Training is recommended to introduce the program and train analysts in computer aided accident reconstruction. Courses in WinCRASH are available on a regular basis from the Institute of Police Technology and Management (IPTM) at the University of North Florida in Jacksonville, Florida. A course can alternatively be given at your work site by special arrangement. Please contact ARSoftware or IPTM for details.

ENDORSEMENT

WinCRASH is currently used as the program of choice for instruction in the "Advanced Traffic Accident Reconstruction With the Use of Microcomputers" course at the Institute of Police Technology and Management (IPTM) at the University of North Florida in Jacksonville.
