          In this paper, study and design of double acting Stirling engine with one piston conducted .The thermodynamic analysis was developed by using MATLAB program for predict the periodic variation of pressure, specific volumes. The performance prediction of the double-acting Stirling engine was developed using ANSYS 18.2 program. This theoretical study mainly studies the influence of the engine parameter (charge pressure) on the engine performances (engine speed, torque, and power output). The performance of the engine was examined for different values ​​of the charge pressures (1, 3, 6 bar). The results indicated the maximum power and torque 117.8 W, 2.5404 N.m at 443 rpm when the charge pressure was 6 bars
