This book was released on 2017-08-17 with total page 55 pages. Available in PDF, EPUB and Kindle. Book excerpt: This thesis deals with control aspects of complex hydromechanical transmissions. The overall purpose is to increase the knowledge of important aspects to consider during the development of hydromechanical transmissions to ensure transmission functionality. These include ways of evaluating control strategies in early design stages as well as dynamic properties and control aspects of displacement controllers, which are key components in these systems. Fuel prices and environmental concerns are factors that drive research on propulsion in heavy construction machinery. Hydromechanical transmissions are strong competitors to conventional torque-converter transmissions used in this application today. They offer high efficiency and wide speed/torque conversion ranges, and may easily be converted to hybrids that allow further fuel savings through energy recuperation. One challenge with hydromechanical transmissions is that they offer many different configurations, which in turn makes it important to enable evaluation of control aspects in early design stages. In this thesis, hardware-in-the-loop simulations, which blend hardware tests and standard software-based simulations, are considered to be a suitable method. A multiple-mode transmission applied to a mid-sized construction machine is modelled and evaluated in offline simulations as well as in hardware-in-the-loopsimulations. Hydromechanical transmissions rely on efficient variable pumps/motors with fast, accurate displacement controllers. This thesis studies the dynamic behaviour of the displacement controller in swash-plate axial-piston pumps/motors. A novel control approach in which the displacement is measured with an external sensor is proposed. Performance and limitations of the approach are tested in simulations and in experiments. The experiments showed a significantly improved performance with a controller that is slightly more advanced than a standard proportional controller. The implementation of the controller allows simple tuning and good predictability of the displacement response.

This book was released on 2005 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydro-mechanical transmissions attempt to balance the productivity increases of hydrostatic transmissions with the higher efficiencies of mechanical transmissions. This technology provides a smooth transition between gear ratios useful to power vehicles of various applications. This balance is accomplished by splitting the input power into two phases, hydrostatic and mechanical transmission. These two phases are then added back together through the use of a planetary gear set. In this study, laboratory experiments were preformed to characterize efficiency and power flow of the hydrostatic and mechanical phases of the transmission. Comparisons of the performance of a hydro-mechanical transmission with the stand alone hydrostatic transmission were made. A mathematical model was also developed to simulate transmission performance which was compared with experimental results. Conceptually, higher efficiencies would be achieved when all of the power is transmitted mechanically, under the assumption of no hydrostatic leakage. The results show this to be true while identifying transmission ranges of maximum efficiency. By being able to model and understand the characteristics of the hydro-mechanical transmission, the design can be optimized to fit different applications. This work also shows that by adding a simple planetary gear set to a hydrostatic transmission, efficiencies and power ranges can both be increased.
