Structural Analysis of Stresses Transferred to a
Basketball Backboard from the Rim by Human Loads
RPI Master's Project First Progress Report
Ryan Ansaldo - 7/4/2012
Problem Description:
•
•
The purpose of this project is to do a structural analysis
of a backboard and compare the stress and deflection
results of 3 common backboard materials
The load chosen will be applied at the furthest distance
on the rim from the backboard to simulate the highest
bending moment.
Modeled Geometry
•
The geometry as specified in the first progress report
was modeled in Abaqus/CAE and is shown in the figure
below.
Modeled Geometry (cont.)
•
The backboard was modeled using 2 parts
•
•
As shown in the figure below, section 1 was created using a 3D deformable
shell while section 2 was created using a 3D deformable solid.
•
This was done for mesh and contact between the rim and backboard
A shell-to-solid coupling was applied at the edges where the 2 sections meet.
Constraints:
•
Rigid body tie constraints were used to tie the surfaces
(highlighted in the figure below) to the reference points
to simulate where a nut and washer would fix the
mounting bracket to the backboard with a threaded pin.
Boundary Condition and Load:
•
•
The backboard was encastred about its edges to
simulate mounted by an aluminum frame to the arms
and base of a basketball stand.
The load is applied at the point on the rim furthest from
the backboard.
Boundary Condition and Load:
•
•
The backboard was encastred about its edges to
simulate being mounted by an aluminum frame to the
arms and base of a basketball stand.
The load is applied at the point on the rim furthest from
the backboard.
Current Results:
•
Von Mises Stress and Deflection in the z-direction
Short Term Goals:
Short Term Goals:
o Run models using different material properties and compare results
o Interpret data and compare results for all three models
