Abstract
Ross-Yorke drive mechanism is composed by the crank disk, the T-type link, the support link and becomes the structure to work a piston using each connecting rod from the side P_h of the T-link expansion piston and the P_c of the side of the compression piston. In this report, it did and it investigated a simulation analysis by this Ross-Yorke drive mechanism about the estimation method in the phase angle and the estimation method of the piston stroke. Moreover, it investigates about transformation Ross-Yorke drive mechanism that a different piston stroke is gotten, too. As a result, we were able to propose the new equation of the experiment of the piston stroke and phase angle.
