artifact description
Inadvertent release is one of the major causes of serious injuries to alpine skiers. The cause of inadvertent release is the repeated flex and counter-flex of the ski and binding, commonly called chatter. Due to current ski binding’s high mass and low natural frequency, they are ill equipped to handle this phenomenon. The results of this project were the design and prototyping of a binding conceived to prevent inadvertent release by increasing the natural frequency of the binding, based on a patent held by Prof. Christopher A. Brown. This project also realized the creation of a vibration-generating machine, which was used to test current ski bindings under a vibrating load.
