Study on the Educational Stirling Engine : Analysis of the Ross-Yoke Mechanism

Abstract

The educational Stirling engine is the simple structure, and it is utilized, as research theme and processing practical training of the high school, as a thermodynamics teaching material of technical college and university, because moreover, it is easily designed and can be produced. The Ross yoke drive mechanism exhibits certain characteristics that make it interesting to obtain compact Stirling engines of satisfactory mechanical efficiency. In this paper, analyzes the effect of each link length of the Ross-Yoke mechanism on piston displacement, and in addition, it is studied on the effect of each link length of the Ross-yoke mechanism on piston displacement, and in addition, it is studied on the effect of each factor on the indicated work using the isotherm model. As the result, the piston displacement showed the tendency away from sine wave, and it was proven that the phase angle changed during the cycle.
