摘要

This paper proposes two analytical methods for studying higher-order accelerations in rigid body plane motion: Euclidean tensors and their representation by complex numbers. The algebraic properties of the complex field with commutative and associative division algebra make this procedure more versatile. The equations that determine the higher-order acceleration field and their properties are presented. The results are in closed-form and coordinates-free. The properties of the velocity, acceleration, jerk, and jounce fields are determined using particular cases.
