Mounting1D

Propagates 1D rotational flange reactions into the 3D frame.

Fixes the flange at angle phi0 and connects frame_a and housing_frame_a. The reaction torque from the 1D flange is projected onto the 3D axis n.

Usage

MultibodyComponents.Mounting1D(phi0=0, n=[1, 0, 0])

Parameters:

Name	Description	Units	Default value
phi0	Fixed offset angle of housing	rad	0
n	Axis of rotation = axis of support torque (resolved in frame_a)	–	[1, 0, 0]

Connectors

• frame_a - Frame3D is the fundamental 3D connector used for 6DOF motion. Most components have one or several Frame

connectors that can be connected together (Frame3D)

• housing_frame_a - Frame3D is the fundamental 3D connector used for 6DOF motion. Most components have one or several Frame

connectors that can be connected together (Frame3D)

• flange_b - This connector represents a rotational spline with angle and torque as the potential and flow variables, respectively. (Spline)

Variables

Name	Description	Units
housing_tau	Reaction torque vector resolved in frame_a	N.m
