Evaluation of Material Selection for Automotive Piston Component using Weighted Sum (WSM) Method

When choosing a material for automobile piston components, be sure to choose one that satisfies all necessary specifications, like durability, resistance to temperature, and wear resistance. To achieve maximum efficiency and effectiveness, factors including cost, weight, and production procedures are also taken into account. Aluminium alloys that are forged iron, and steel are common material for piston components; each has certain benefits and compromises in terms of expense and efficiency. Introduction: Material selection for auto piston components is critical to ensuring top performance and long-term durability. The piston, as a vital engine component subjected to high temperatures, hardship, and wear and tear, necessitates a material that promotes efficient combustion, lowers friction, and maintains its structural integrity. When selecting materials for automobile pistons such as aluminium alloys, wrought iron, or steel, aspects such as heat conductivity, resistance to wear, size, expense, and manufacturing capability are carefully considered to satisfy the specific needs of the application. Research Significance: Aluminum, steel, along with iron are the better frequently used goods for pistons. The effort from the expanding gas at great heat matters about the inside. Cylinder and many other important factors determine proper piston selection Material necessity are balanced more demanding, just as no single material meets all the properties required for a distinct application. Method: The weighted sum method is a decision-making approach that involves assigning weights to different criteria or objectives and combining them to make an overall assessment. It allows decision-makers to prioritize and balance various factors based on their relative importance. By utilizing this method, complex decision problems can be simplified and converted into a single weighted score, facilitating a clearer understanding of trade-offs and aiding in the decision-making process. Alternate Parameters: “LM-26 alloy + 0% Porcelain, LM-26 alloy + 2% Porcelain, LM-26 alloy +4% in weight Porcelain, LM-26 alloy +6 percent by weight porcelain, and LM-26 alloy +8 percentage of weight Porcelain”. Evaluation Parameters: Hardness, Compressive strength ,Tensile strength ,Specific wear rate , and Friction coefficient Result: “LM-26 alloy +6 wt.% Porcelain” is in the 1st Rank, “LM-26 alloy +4 wt.% Porcelain” in the 2nd Rank, “LM-26 alloy +2 wt.% Porcelain” in the 3rd Rank, “LM-26 alloy +8 wt.% Porcelain” in the 4rth Rank, and “LM-26 alloy +0 wt.% Porcelain in the 5th Rank”. Conclusion: For the Material Selection for Automotive Piston Component : “LM-26 alloy +6 wt.% Porcelain” is in the 1st Rank, “LM-26 alloy +4 wt.% Porcelain” in the 2nd Rank, “LM-26 alloy +2 wt.% Porcelain” in the 3rd Rank, “LM-26 alloy +8 wt.% Porcelain” in the 4rth Rank, and “LM-26 alloy +0 wt.% Porcelain in the 5th Rank”.
