Condition Monitoring and Fault Diagnosis Applications
The objective of this project was to develop a complete 3D CAD model of an electric powertrain which should be used later on for FEM-based fault diagnosis applications.
The project was carried out the summer of 2018, to assist PhD student Jagath Senanayaka with research project on condition monitoring and fault diagnosis applications. The objective of this project was to develop a complete 3D CAD model of an electric powertrain which should be used later on for FEM-based fault diagnosis applications.
The main components of the electric powertrain are the electric motor and the gearbox, and a systematic 3D model should be constructed for each single parts of the powertrain. SolidWorks was used to produce the 3D models and also to assemble each of the parts together in a 3D-assambly.
The project started off by disassemble all parts both on the gearbox and electrical motor. A slide caliper with accuracy of 0.05mm was used to the measure the parts dimensions. Some details where ignored in the construction of the 3D model due to the fact that it should be used in a FEM simulation later on, and was not considered as a essential detail to include in the simulation. The gearbox and electrical motor housing were separated with a band saw to be able to measure the dimension and details inside these components. All pinion, gear, bearing, circlip and shaft-key were imported from the toolbox provided by SolidWorks.
A 3D model containing all parts from the powertrain was constructed in accordance to the dimensions of the physical powertrain.
