Abstract

Casting motion, an up-and-down rotation of a rod, is one of the motions using the dynamics of a pendulum under gravity. This report examines the property of the casting motion using a simple system that consists of a rigid rod and a point mass pendulum. The rigid rod rotates around one end by an actuator, while the point mass pendulum can rotate freely around the other end of the rod. The rotational motion of the rigid rod is determined as polynomial function of time. Calculated results demonstrate that there is an optimal landing position of a mass that minimizes the landing velocity. Experimental study is also performed to verify the validity of the analytical model. The experimental results agree with the calculated results.
