Abstract
The project mainly deals with the design, analysis of piston. A piston is a component of reciprocating engines, reciprocating compressors and pneumatic cylinders among other similar mechanisms. In an engine, its purpose is to transfer force from expanding gas in the cylinder to the crankshaft via a piston rod/and or connecting rod. Here the piston is designed, analyzed and the manufacturing processes have been studied. Piston temperature has considerable influence on efficiency, emission, performance of the SI engine. Purpose of the investigation is the measurement of piston transient temperature at several points on the piston, from cold start to steady condition and comparison with the results of finite element analysis.
In this project, Aluminium Silicon Carbide (AlSiC), an Aluminium matrix composite is used as an alternative for Aluminium. A 3D model was made using CREO 4.0 and Structural and thermal analysis was done on ANSYS. Compared to Aluminium, AlSiC has better abrasion resistance, creep resistance, dimensional stability, exceptionally good stiffness-to-weight and strength-to-weight ratios and better high temperature performance. Fabrication of piston using AlSiC is also easier than using Aluminium. The effect of high temperature on mechanical properties of silicon carbide particulate reinforced cast aluminium alloy composite is analysed.
