Rampco - Deliverable D2.1

The present deliverable "D2.1 Report with detailed specifications of traction system" is dedicated to the description of the design phase of the RampCo platform that includes both specifications for the traction system and the detailed design of some components. The platform concept developed and reported is the "cart" concept, as introduced in D1.2. The core component reported are the balancing mechanism, which is designed for keeping the horizontal attitude of the platform during operations, and the independent traction unit based on tracks and make the cart concept self- actuated on top of a passive ramp. All reported components are in form of detailed mechanical drawing tables. The actuation units (balancing actuator and traction motor) are selected form commercial products and reported in form of preliminary bill of materials. The cart design concept has the advantage of modularity, providing symmetrical and separated motor functions on both sides of the platform. This approach enables the possibility to assemble the platform in case of split transportation of subparts of the system. The present report includes also the design data (forces and stresses) obtained by the simulation in realistic conditions of the design model, in order to provide force profiles for the composite materials selection and testing. Reported results have regularly been exchanged and discussed with all the partners during the periodic technical meetings (M3, M6) and web sessions, and are preparatory for the prototyping and integration phases taking place from M8 to M14 (end of WP2).
