30.7.2. Speed Sensor

This sensor is to measure the velocity of chain link that pass the range of speed sensor and is the nearest to speed sensor.

\(\mathrm{v}_{0}=\mathrm{f}_s^{\mathrm{T}} (\mathrm{V}_{\mathrm{c}}-\mathrm{V}_{\mathrm{s}})\)

where, \(\mathrm{v}_{0}\) is the result of sensor. \(\mathrm{V}_{c}\) is the velocity of the center marker of the closest body of sheet bodies in the range of the sensor and \(\mathrm{V}_{s}\) is the velocity of sensor center position. \(\mathrm{f}_s^{\mathrm{T}}\) is the specified direction of the sensor.

30.7.2.1. Modeling Options

The user can create a speed sensor as follows.

  • Point, Direction, Distance

    • Point: Selects a point on a body to define the center of speed sensor.

    • Direction: Defines a direction of speed sensor.

    • Distance: Defines a range of region to measure output.

    Note

    The user should define the sensing target entity by using Speed Sensor property page.
