Control-Oriented Automatic Transmission- Based Powertrain Modeling And Simulation With Judder, Harshal B. Kundale
Control-Oriented Automatic Transmission- Based Powertrain Modeling And Simulation With Judder, Harshal B. Kundale
Masters Theses
This work presents automatic transmission-based powertrain modeling. The powertrain consists of an engine, torque converter with lock up clutch, transmission gearbox, propeller shaft, and vehicle body. Simplified powertrain component models are developed for vehicle powertrain dynamic response analysis and future control work. The powertrain components are modeled with algebraic and first order non-linear differential equations. A MATLAB-based powertrain simulation system is developed to investigate the transient characteristics during lock up of torque converter. Simulation results are used in the determination of effects of judder on torque and angular velocity. Clutch judder is a self-excited vibration that occurs during the clutch …
Forward-Looking, Velocity-Driven, Powertrain Modeling And Optimal Control For Continuous Variable Transmission, Paresh Deshmukh
Forward-Looking, Velocity-Driven, Powertrain Modeling And Optimal Control For Continuous Variable Transmission, Paresh Deshmukh
Masters Theses
This thesis is the second part of a two-part study focused on improving Continuous Variable Transmission (CVT) ratio management and control. The objective of the overall project was to develop a methodology for a vehicle with a CVT and a downsized gasoline engine to deliver the maximum vehicle fuel economy within drivability and performance constraints. The first part of this study, as described in [1], focuses on developing a cycle driven model for optimizing the CVT ratio. The study presented in this paper focuses on developing a velocity driven model to simulate the real-time behavior of a vehicle. The results …
Implementation And Analysis Of A 1.4l Turbo Liquid Cooled Cac And Ac Condenser System, Mitchell Zajac
Implementation And Analysis Of A 1.4l Turbo Liquid Cooled Cac And Ac Condenser System, Mitchell Zajac
Masters Theses
This project report serves as a continuation and finalization of an overall experience with the design process including working on the development of system components, working with automotive industry leaders, suppliers and dealing with the aspects of business and production feasibility. The development of a dual level cooling concept to apply Centro Richerche Fiat established components on a Chrysler Group vehicle application was the foundation of the design project completed in December 2012 by Matt Cutler and Mitch Zajac. The development of this system aimed to decrease overall vehicle power consumption, minimize overall system packaging space, and to increase vehicle …
