摘要

文摘：本文首次引入了对偶数四元数形式的拉格朗日动力学方程。此外，本文还引入了对偶四元数格式的瑞利耗散函数，考虑了耗散（非保守）力，如通过粘性流体的运动、摩擦和弹簧阻尼力。以对偶四元数为例，推导了机器人机械手的拉格朗日动力学方程。

Dual Quaternions Representation of Lagrange's dynamic equations

Abstract' This paper introduces for the first time, the Lagrange's dynamic equations in dual number quaternion form. Additionally, Rayleigh's dissipation function in dual quaternion form is introduced here allowing for the accounting of dissipative (non-conservative) forces such as motion through a viscous fluid, friction, and spring damping force. As an example, dual quaternions are used here to derive the Lagrange dynamic equations of a robot manipulator.
