The purpose of an oil sump is to lubricate the engine components such as drive systems, timing gears, crankshafts. And it also helps the engine to cool and free from corrosion. It acts as a reservoir and circulates the oil to engine components.
The 3D-CAD Model is imported from the Grad-Cad. The CAD Model was modelled in CATIA-V5 and it’s used for analyzing.
The dimensions of the Model are as follows:
• Height = 300 mm, Width = 125 mm, Height = 91.78 mm.
The following details are used for Meshing:
• Mesh Type: Tet-Dominant
• Element Sizing: Moderate Mesh
• Element Order: First Order
• Total Number of Nodes: 49362
• Total Number of Faces: 92956
Since the size of the geometry is greater in size moderate mesh is used to reduce the computation time to obtain the results.
Boundary conditions without Preload
The above figure represent the Eigen Frequencies and Eigen Modes for the components. The above frequency values are derived without any preload.
Boundary conditions with Preload
The above figure represents the Eigenfrequency graph with Preload constraint.
The Eigen frequencies with Preload constraints is increased when compared with Eigen frequencies without Preload constraints. The constant static load helps to increase the frequency of the structure. The value of Preload Boundary condition is obtained from Static Analysis.
