LineForceWithMass

General line force component with a point mass on the connection line

Description

This component is used to exert a line force between the origin of frame_a (left) and the origin of frame_b (right) by attaching components of the 1-dimensional translational mechanical palette (Mechanics/Translational) between the two flange connectors flange_a (top left) and flange_b (top right).

There is a point mass on the line connecting the origin of frame_a and the origin of frame_b. This point mass approximates the mass of the force element. The distance of the point mass from frame_a as a fraction of the distance between frame_a and frame_b is defined via parameter lengthFraction (default is 0.5, i.e., the point mass is in the middle of the line).

Parameters

    LineForceWithMass_0

  • m [kg] : Mass of point mass (> 0) on the connetion line between the origin of frame_a and the origin of frame_b (m): Scalar.
  • lengthFraction [1] : Location of point mass with respect to frame_a as a fraction of the distance from frame_a to frame_b (lengthFraction): Scalar.
  • s_small [m] : Prevent zero-division if distance between frame_a and frame_b is zero (s_small): Scalar.
