The main objective of this research is to study the stresses due to action of gas pressure, major thrust pressure of the piston, and thermal load in wet liner cylinder of Perkins 1306 diesel engine as a real case. Two materials namely cast iron, grades C4 28-48 and cast alloy steel, C4 35-56, grade 38XMIOA are considered. The finite element package ANSYS (19.1) has been used as a numerical method to calculate the stresses and deflection in 3D liner model.
The numerical results show that the maximum deflection occurs at a point of applied piston load in which it is 0.135 mm for cast iron and 0.109 mm for steel. The deflection in circumferential is very small varied in range (-0.9 to 0.9) % of maximum deflection , and the maximum axial deflection for cast iron and steel are 0.66 mm and 0.67 mm, respectively. In addition, confirming the reliability of developed PTC MATHCAD 4 program by consider one verification case. These results show that a good agreement between the numerical and analytical methods.
