n8walker Posted February 24 Posted February 24 (edited) Hello everybody, among other things, the company I work for uses a hexapod for vibrational and fatique analysis of car parts like hood, doors, interior, etc. A hexapod can control all six degrees of freedom of the tested device, which allows you to recreate various driving situations and loads without the need of the real car. This contest inspired me to recreate such a device in lego. Whilst obviously switching from hydraulic to pneumatic, everything else should be as realistic as possible. This meant, that unlike other lego-hexapods out there, I had to go for stationary cylinders. (You do not want moving cylinders in vibrational analysis due to inertia and damping effects of the cylinders, as well as wear on the hydraulic hoses) The most difficult part was to get the angles of the cylinders right so the table can have a maximum of movement without the cylinders and the linkage getting in the way of each other.
