A Bearing is essentially a two-spring-damper system that is aligned in any two coordinate axes of a coordinate system: primarily a rotating plane.
For rotations in the X-Y plane, the result items for the first axis are in X direction and the results for the second axis are in Y direction. The application adds a suffix (number 1 and 2) to each result item. The X-Z and Y-Z rotation planes also use this convention.
You can use a Bearing probe to display the following result items.
- Elastic Force 1
The force is calculated as (Spring Stiffness * Elongation). The force acts along the length of the spring along the first axis.
- Elastic Force 2
The force is calculated as (Spring Stiffness * Elongation). The force acts along the length of the spring along the second axis.
- Damping Force 1
Damping force is calculated as (Damping Factor * Velocity) and acts to resist motion along the first axis.
- Damping Force 2
Damping force is calculated as (Damping Factor * Velocity) and acts to resist motion along the second axis.
- Elongation 1
The elongation is the relative displacement between the two ends of the spring in the first axis. The elongation could be positive (stretching the spring) or negative (compressing the spring).
- Elongation 2
The elongation is the relative displacement between the two ends of the spring in the second axis. The elongation could be positive (stretching the spring) or negative (compressing the spring).
- Velocity 1
Velocity is the rate of stretch (or compression) of the spring in the first axis. This quantity is only calculated in a Transient Structural analysis.
- Velocity 2
Velocity is the rate of stretch (or compression) of the spring in the second axis. This quantity is only calculated in a Transient Structural analysis.
