LADD TRANSMISSIONS - DESIGN, MANUFACTURE, AND NEW COMPLIANCE MODELS

We introduce new compliance models for LADD transmissions which reduce inelastic model errors by an order of magnitude. These errors are due to fiber bending, as opposed to the traditionally assumed fiber elast icity. The new LADD models are experimentally verified and applied to the modeling of concentric LADD devices. The new models are essential for the design of LADD based systems, the online estimation of LADD fo rces, and accurate control. Details of the design, manufacture and bre ak-in phenomena are given, as well as the first experimental measureme nt of LADD efficiency, which is better than 90%.
