Moose Crash Test Dummy - VTI

Figure 5: Sketch of rubber plate (cross-section).Each plate has the shape of an ellipse. It is possible that a drop shapedcross-section could describe the body even better, but this is plainspeculation. The dummy is intended to be a simplified model of a reallifemoose. Main characteristics have been given priority causing manydetails to go out of focus. With a model simplified correctly one canhopefully conduct crash tests without getting unpleasant surprises.Another issue of huge importance is that chance must not interferewhen testing passenger cars.With the legs disregarded a moose has its vertical center-of-gravityapproximately in the center of the body. The moose’s specificationsvary significantly due to the food supply and time-of-year. The body isdense and compact with exception of the belly, which is easy to deformyet heavy. To create a rubber plate that fulfills these specificationshollow sections are distributed over the sheet. The top half has cavitiesfocused to the center while the lower section has cavities in the outerregions. (See figure 5) This causes the lower part of the dummy to beinitially soft, while the top part appears more solid. Still the center-ofgravityremains approximately in the center.VTI Särtryck 342A 19
