Modelling and Simulation of Marine Cables with Dynamic Winch and Sheave Contact
Cable-sheave systems are commonly used on marine vessels for lifting and towing applications. As a result of the motion of the vessel, the cable can detach from the surface of the sheave. This thesis presents a simulation of a towed cable system which includes the interaction of the cable with the …

An Investigation of Improving Wear of 390 Die-cast Aluminum Through Hardcoat Anodizing
… localized wear groove in the stock CVT drive sheave with little wear occurring elsewhere. The Hardcoat anodized CVT drive sheave did not show evidence of a significant localized wear groove as the stock sheave but indicates that wear occurred more evenly across the surface. This wear is …

An Investigation of Wear-Resistant Coatings on an A390 Die-Cast Aluminum Substrate
… the wear life of A390 aluminum primary clutch sheaves used in continuously variable transmission (CVT). The coatings tested were: hard chrome, electroless nickel metal, hard coat anodizing and composite ceramic coating. The primary clutch sheave material is a die-cast A390 aluminum. A wear test …

Bond graph modeling of hydraulic circuits on a sweet sorghum harvester
… for several combinations of motor, pump, and sheave ratio. A 7.3 cm³/rad motor, 2.53 cm³/rad pump , and 2:1 sheave ratio produced the correct disk-cutter speed, and low torsional vibration when cutting the stalks, consequently this combination was selected for the design.

Modelling and Prediction of the Effects of Dynamic Responses of Tall Buildings on an Elevator System
… comprised of the elevator car, compensating sheave, and counterweight connected by the suspension and compensating ropes were derived. A method to account for the nonstationary and nonlinear nature of the elevator system was developed. The linear and nonlinear phenomena were observed. The …

An Experimentally-Validated V-Belt Model for Axial Force and Efficiency in a Continuously Variable Transmission
… efficiency and design parameters, such as sheave angle. The goal of this thesis is to create an improved V-belt model that may be used as a design tool. This model provides quantitative information about efficiency that can be used to make more informed design decisions. The belt model also …

The Modelling and Simulation of the Dynamic Behaviour of a Lift Car-Rope Suspension System
… caused by building sway, excitation at the sheave from the drive machine and excitation at the car due to the car-guide rail interaction. These various sources of excitations may lead to an adverse dynamic behaviour of the lift system due to its nonlinear and nonstationary …

Modellierung und Simulation der Beanspruchung von Zugsträngen aus Stahllitze für Zahnriemen
In dieser Arbeit wird das Verhalten von gewickelten Seilen aus Stahllitze unter Zug- und Biegebelastung mit Hilfe der Methode der Finiten Elemente untersucht. Ausgehend von dem Modell einer einfachen Litze mit einem Kern- und sechs Außendrähten erfolgt eine ausführliche Analyse der …
