principalMomentsOfInertia

R2026b

Class: simscape.multibody.MassDistribution
Namespace: simscape.multibody

Compute principal moments of inertia

Since R2022a

Syntax

pmoi = principalMomentsOfInertia(md)

Description

pmoi = principalMomentsOfInertia(md) computes the principal moments of inertia of the provided simscape.multibody.MassDistribution object, md.

Input Arguments

md — Mass distribution

simscape.multibody.MassDistribution object

Mass distribution, specified as a simscape.multibody.MassDistribution object.

Output Arguments

pmoi — Principal moments of inertia

simscape.Value([I_xx I_yy I_zz]',"mass*length^2")

Principal moments of inertia about the center of mass, returned as a simscape.Value object that represents a 3-by-1 array with a unit of mass*length^2. The principal moments are the eigenvalues of the inertia matrix and correspond to the moments of inertia about the principal axes.
