Stress Analysis on Cylinder Head

Experimental investigation is carried out on computerized VCR diesel test rig to determine the variation of pressure with crank angle in the cylinder at different compression ratios. The temperature variation of gases was further evaluated using the results obtained from the experimentation. Using this experimental observations and the actual dimension of cylinder head, stress analysis was carried out with the aid of the modern software CATIA and ANSYS. The stresses induced in cylinder head and deformations were found to be within allowable limits. The stress analysis of the cylinder head was carried at five different materials of compression ratio 18.5. What they are CGI(GJV 450), GREY CAST IRON, A319-T5, A356-T6 and AMC-SC1. Through the analysis above five different materials aluminum alloy(a356-t6) gives better results. The following inferences are drawn from the study. 1. The stresses induced in the cylinder head at compression ratios 18.5 is 42.381 Mpa. 2. Through the heat transfer analysis. it was observed that maximum temperature in the cylinder head occur at the compression ratio of 18.5 of value 348.14 0 C.
