    Defines dampings for each constrained degree of freedom for a Track System.

    tensile - Attenuation factor for longitudinal tension/compression.
              Damps high-frequency oscillations during stretching and compression of track segments.

    bending_vertical - Damping for bending around the VERTICAL axis.
                       Damps oscillations in side-to-side bending of the track.

    bending_lateral - Damping for bending around the LATERAL axis.
                      Damps oscillations in sagging (bending across track width).

    shear_vertical - Damping for shear deformation along the VERTICAL axis.
                     Damps oscillations in shear deformation across the track height.

    shear_lateral - Damping for shear deformation along the LATERAL axis.
                    Damps oscillations in shear deformation across the track width.

    torsional - Damping for torsional deformation around the main track longitudinal axis.
                Damps oscillations in twisting of the track about its longitudinal axis.


    vertical_bushing_damping         -  Scales the viscous damping in the vertical
                                        movement between track links, representing
                                        velocity-dependent energy dissipation in
                                        inter-link bushings. This is a scaling parameter
                                        with default value of 1.
                                        Increaset this value if you experience
                                        excessive vertical oscillations of the track links.
                                        Decrease this value if the track becomes overly
                                        damped, observed as a sluggish vertical response
                                        and a slow return to equilibrium after excitation.
    min_normal_force                 -  minimum normal force used in dissipation calculation.
    bending_friction_coefficient     -  scales the dissipative force between track links
                                        based on the normal force.

    The friction limit in the dissipation is:
        f_L = normal force * bending_friction_coefficient

    The normal force is computed as:
        max(F_n, min_normal_force)

    Note: dissipation scales with 1 / (track node mass)^2.
