# SS-V: 5090 Bushing Stiffness

Test No. VNL10 Find the rotation of cylinder subjected to a moment of 10 N-m along its length.

## Definition

The cylinder is connected to a grounded spring with the following stiffness:

- X
- 100 N/m
- Y
- 100 N/m
- Z
- 100 N/m
- Rot X
- 10 N-m/rad
- Rot Y
- 10 N-m/rad
- Rot Z
- 10 N-m/rad

The units are SI.

Dimensions: D = 443.3 mm, H = 231 mm

The material properties are:

**Properties****Value**- Modulus of Elasticity
- 2.05e11 pa
- Poisson's Ratio
- 0.3

## Results

Grounded bushing with above referenced stiffnesses is applied on one end of the
cylinder and a remote load of 10 N-m about the cylinder axis is applied on the other
end, as shown in Figure 2.

Datum points are created along the circumference of the cylinder. Rotation between
the points is measured to calculate the rotation of the cylinder due to applied
moment load.

The following table summarizes the rotation of the cylinder.

Rotation of Cylinder (rad) | 1 | 1 (57.3 degrees) |

*The reference is calculated by hand using a rotation of 1 radian about the cylinder axis.
