The Kinematic Design of Automatic Gear Transmissions for Bicycles

Recently, bicycles are used as exercising machines and traffic vehicles. Planetary gear trains can be used as the transmission systems for bicycles. The purpose of this work is to propose a design methodology for the kinematic design of automatic gear transmissions with planetary gear trains for bicycles. First, applying the check list method (combining and extending methods), the design concep...

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 ber bending, as opposed to the traditionally assumed ber elasticity. The new LADD models are experimentally veriied and applied to the modeling of concentric LADD devices. The new models are essential for the design of LADD based systems, the online est...

Hf Xl: Adaptive Wideband Hf Transmissions

This paper presents a solution to increase the throughput of an HF (High Frequency) physical (PHY) layer in particular to allow for services such as IP over HF. Additionally, this new PHY layer can improve the adaptability of the waveform to the channel variations, in particular to limit the retransmissions due to errors. Taking into consideration the existing HF spectrum occupancy and its high...

Velocity Dependence of Joint Friction in Robotic Manipulators with Gear Transmissions

This paper analyses the problem of modelling joint friction in robotic manipulators with gear transmissions at joint velocities varying from close to zero until their maximum appearing values. It is shown that commonly used friction models that incorporate Coulomb, (linear) viscous and Stribeck components are inadequate to describe the friction behaviour for the full velocity range. A new frict...
