Collision Analysis
MADYMO (MAthematical DYnamical MOdel) is a highly complex computer modeling program that can be used to analyze the movement and injury response of the human body to impact. Collision Analysis' experts are skilled in using this powerful tool to enhance biomechanical investigations.

MADYMO's uses in forensic biomechanics include the analysis of:

seatbelt misuse, non-use, and failure
late airbag deployment
frontal, side, and rear impact collisions and rollovers
all-terrain vehicle crashes
bicycle and pedestrian impacts

The best way to understand MADYMO's capabilities is to examine animations output by the engineering model. Click on the desired frame to view the animation.

Frontal collision, belted driver with airbag
Video 1 In this animation of a frontal impact, the interaction of the driver with the seatbelt and deploying airbag is clearly demonstrated. The full duration of the collision is shown (approximately 100 milliseconds or one tenth of a second).
Frontal collision, belted passenger without airbag
Video 2 This model shows a belted passenger subjected to a frontal collision. The interaction of the occupant with the seatbelt and knee bolster is highlighted. It uses a very accurate seatbelt model that can correctly simulate the seatbelt sliding on the occupant.
Frontal collision, seatbelt misuse
Video 3 MADYMO can be used to investigate the effects of seatbelt misuse on injuries. In this model, the occupant is subjected to a frontal collision but the shoulder belt portion of the seatbelt restraint has been removed, simulating a common situation where an occupant wears the shoulder belt behind his back for comfort.
Side-by-side all-terrain vehicle rollover, belted driver
Video 4 MADYMO can model more than just passenger cars. This is a very simple model of a belted occupant subjected to a 90 degree rollover in a side-by-side all-terrain vehicle.
Vehicle rollover, belted driver
Video 5 Vehicle rollovers are chaotic events in which occupant kinematics and dynamics can be difficult to determine without the use of a sophisticated simulation program. MADYMO can greatly enhance the accuracy of a biomechanics rollover analysis.
Rear impact, unbelted driver
Video 6 This detailed animation demonstrates an unbelted occupant's motion during a rear impact. In this model, the neck hyperextends because there is no head restraint to stop the head's rearward motion. Similar motion can be expected in a vehicle with a poorly designed or improperly adjusted head restraint.

A MADYMO analysis is much more than a computer animation. Computer animation software has no understanding of the physical laws that govern our world. A MADYMO animation follows the laws of physics to find a mathematical solution based on specific case conditions provided by the user. This can be a very important issue in determining admissibility in the courtroom.

In addition to realistic animations of human movement, MADYMO provides detailed quantitative information of injury forces.

MADYMO is a sophisticated program that requires an expert knowledgeable in the underlying laws of physics and the fine details of a computer solution. Collision Analysis can provide this level of expertise.
