Hood Latch

Structural Analysis on a Hood Latch

Geometry and Meshing

The Geometry is loaded into ANSYS Workbench from Solidoworks. The geometry was provided as a solidworks prt file.

The Mesh is created with the element size as 0.04 cm. After the generating the mesh didn't seem adequate so the circular edges had their shapes added for Refinement. An extra insert-able option.

Constraints

Cylindrical Support is added to the upper and lower holes so that in real-life the deformation wont let these features to be deformed for there are features extend within the holes so as to hold the hood in place.

Cylindrical Support adds in:

Radial-direction-relative-to-cylinder Support (Fixed)

- Cylinder is Free to Move, Rotate and Deform Axially and Tangentially

Axial-direction-relative-to-cylinder Support (Fixed)

- Cylinder is Free to Move, Rotate and Deform Radially and Tangentially

Tangential-direction-relative-to-cylinder Support (Fixed)

- Cylinder is Free to Move, Rotate and Deform Radially and Axially

Frictionless Support is added to the lower holed-edged features. this allows the hood latch to rotate frictionlessly as a feature holds the hood latch in its place by holding it upon these flat surface blue highlight on the figures to the right.

Frictionless Support adds in:

Normal-direction-relative-to-surface Support

- Surface is Free to Move, Rotate and Deform tangential to the Surface

A force of 360 dynes is applied perpendicular to the red highlighted surface. The components when oriented according to the axes the components are represented in the figure to the left.

Results

Equivalent Elastic Strain

Equivalent Elastic Strain caused due to the constraints applied to the geometry. The Maximum Value is 7.3379e-8 with the Minimum Value is 4.9102e-12.

A Zoom-In to the region that is important to this Quality of Result

Total Deformation

Contour of Total Deformation, where the red region represents the maximum deformation of 3.6989e-7 cm and the blue region represents the minimum deformation of 3.3468e-9 cm.

A better view of the contour of the Total Deformation caused within the Geometry due to the Constraints applied on it.

Vector Graph for Total Deformation. The arrows point clockwise for the upper hole and anti clockwise for the lower whole hole.

This is a better representation of the comment about the direction of the arrow for the Vector Graph for Total Deformation.

Safety Factor

Safety Factor Graph which is a singular value of 15.

Modal Analysis

The X-axis represents the number of Total Deformation caused and the Y-axis represents the frequency of Total Deformation in the graph to the left. To the right it is represent in a table form.
