For our Major Qualifying Project, me and a group of two other mechanical engineers are working on a project to design and build a new ski brake. We've noted that the main problems are durability and that ski brakes are only designed to handle forces in the forward direction.
In addition to durability, we feel that one of the main problems is that there is no spring to absorb forces that are created during switch falls. This combined with the angle of the brake creates an anchor that results in forces and moments that are above the critical limits of the binding. Often the brake assembly will snap off or brake arms will bend. Our goal is to take a look at the standards for falls in the forward direction and apply them to switch falls as well.
In order to develop a starting point we need you help!
1) How common of a problem is this for freeskiers? Is this an important issue to address?
2) Why do you think freeskiers are more prone to breaking ski brakes?
3) Stories of broken ski brakes
4) Stories of run away skis that created a safety hazard
5) Any pictures of broken ski brakes
Any input, stories, ideas or advice is GREATLY appreciated
Thanks NS!
