Abstract
A procedure to predict the response of the elastic coupler of a four-b ar linkage allowing for possible fluctuation in crank speed is present ed. The response is described by Mathieu-Hill equations obtained by ap plying Hamilton's principle and method of Kantorovitch. These are solv ed by the RKM-method of numerical integration. The effect of crank ine rtia on coupler response is studied. It is concluded that crank speed fluctuation gives rise to increased strains and hence should be contro lled by suitable crank inertia.
