Model Advancement And Hil Setup For Testing A P2 Phev Supervisory Controller, Sajjan Balakrishnan
Model Advancement And Hil Setup For Testing A P2 Phev Supervisory Controller, Sajjan Balakrishnan
Wayne State University Theses
Teams participating in Advanced Vehicle Technology Competitions such as EcoCAR3 are often bound by limited time and resources. Moreover, vehicle and component downtime due to mechanical and electrical issues reduce the time available for testing activities demanded by the Controls/Systems Modeling and Simulation teams. Therefore, the teams would benefit from identifying new approaches and being more pragmatic and productive in order to achieve satisfactory progress in the competition. This thesis summarizes the approach taken to improve the simulation accuracy of the Wayne State University EcoCAR3 team’s Pre-transmission Parallel Hybrid Electric Vehicle plant model and HIL setup. Focus is on testing …
The New Designing Of The Nano-Indentation Method To Applying On The Aisi D-2 Steel, Tangyue Wu
The New Designing Of The Nano-Indentation Method To Applying On The Aisi D-2 Steel, Tangyue Wu
Wayne State University Theses
In this thesis, it is mainly to describe the new designed nano-indenataion. This kind of nano-indentation apparatus is much more inexpensive and almost has the same function to compare with the commercial one. The nano-indentation system can get the force-displacement wave, which is the way to determine the elastic and plastic properties for the particle materials. In the structure, it would describe the designing of the nano-indentation apparatus for a big partial of the thesis. This part is divided into 3 sub-part: hardware designing, software designing and data processing. The material, D2, is chosen to do the force-displacement wave, which …
Development Of Hybrid Supervisory Controller And Energy Management Strategy For P2 Phev, Guilin Zhu Zhu
Development Of Hybrid Supervisory Controller And Energy Management Strategy For P2 Phev, Guilin Zhu Zhu
Wayne State University Theses
The EcoCAR3 project is a four-year competition sponsored by General Motors and the U.S. Department of Energy challenging 16 universities teams to reengineer a 2016 Chevrolet Camaro to be a performance plug-in hybrid electric vehicle. A pre-transmission (P2) without clutch parallel architecture was chosen by Wayne State University EcoCAR3 team in Year 3.
The parallel PHEV architecture was modeled by using MATLAB, Simulink and Stateflow for the MIL and SIL environment which was used to test different control strategies. To efficiently distribute the power between engine and electric motor and assess component and system statuses, a hybrid supervisory controller was …
Combustion Phasing Through Combustion Ionization In A Caterpillar C7 Compression Ignition Engine, Kamal Ashraf Assaad
Combustion Phasing Through Combustion Ionization In A Caterpillar C7 Compression Ignition Engine, Kamal Ashraf Assaad
Wayne State University Theses
To achieve the goals of best fuel economy, peak power and low soot emissions in military engines it is necessary to control the combustion process. An in-cylinder combustion sensor is required to achieve the goals of controlling the combustion process. Over the last four decades, in-cylinder pressure transducers and ion current sensors have been available for research and development. Most of the effort has focused on the pressure transducer, however up till now a pressure transducer suitable for use in production engines has not been developed yet, because of cost and durability concerns.This work presents the analysis of experimental data …
Turbulent Spray Combustion Modeling Using Direct Integration Of Chemistry And Flamelet Generated Manifolds, Ashraya Goyal
Turbulent Spray Combustion Modeling Using Direct Integration Of Chemistry And Flamelet Generated Manifolds, Ashraya Goyal
Wayne State University Theses
Turbulent spray combustion of n-dodecane was modeled at engine relevant conditions using various combustion models (Direct Integration of Chemistry and Flamelet Generated Manifolds) and turbulence models (Dynamic Structure Large Eddy Simulation and RNG Reynolds-Averaged Naiver-Stokes). A recently developed n-dodecane mechanism was utilized and the turbulent spray was simulated at various combustion chamber initial gas temperature and pressure conditions. Mesh with size of 31 microns was utilized to resolve small eddies around the spray. The pressure-based ignition delay, flame lift-off length, and spray and jet penetrations were studied and compared with experimental measurements. The Direct Integration of Chemistry and Flamelet Generated …
