Cantilever Beam Modal Analysis
Created using ANSYS 13.0
Problem Specification
Consider an aluminum beam that is clamped at one end, with the following dimensions.
Length |
4 m |
|---|---|
Width |
0.346 m |
Height |
0.346 m |
The aluminum used for the beam has the following material properties.
Density |
2,700 kg/m^3 |
|---|---|
Youngs Modulus |
70x10^9 Pa |
Poisson Ratio |
0.35 |
Using ANSYS Workbench find the first six natural frequencies of the beam and the mode shapes.
