| Summary |
"Energy absorption by driving an oversized plunger through a longitudinally slit shell has been studied. The characteristics obtained by conducting several runs indicate that such a system could be used for energy absorption and for limiting the force required to drive the plunger through the shell. The characteristics can be readily altered by changing the dimensions of the tube. Details of the experimental set-up have been given. Such an absorber has been adapted for mitigating injury sustained by the occupants in the interior of a colliding vehicle. Full advantage has been taken of the "Ride down" potential available to the occupant if he comes into contact with the interior of the vehicle before the vehicle comes to a stop. An analysis of the ride down has been made on the assumption of a suitable mathematical expression for the deceleration of the intact portion of the vehicle. A brief study of the existing restraint systems has been made and two passive restraint systems have been proposed which alleviate some of the inherent drawbacks of the existing systems. One of the systems proposed eliminates the need for a sensor currently used to trigger airbags"--Abstract, leaf ii. |
