19.5.19.7. Bearing Probes

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.
