PEMLIHAN MATERIAL UNTUK LANDING GEAR PESAWAT

Abstract

Landing gear is a crucial component of an aircraft, serving as the primary support while on the ground, particularly during landing and taxiing. The selection of an optimal material for landing gear is a critical factor in ensuring safety, efficiency, and reliability. This study aims to evaluate several candidate materials using Ansys Granta Selector software, which enables the analysis of mechanical properties, cost, and other parameters.The materials analyzed include Titanium Alloy (Ti-6Al-4V), Steel Alloy (AISI 4340), Aluminum Alloy (AA7075), Nickel-Based Superalloy (Inconel 718), and Carbon Fiber Reinforced Polymer (CFRP). The evaluation is based on properties such as fracture toughness, fatigue strength, yield strength, maximum service temperature, specific stiffness, and cost. The analysis results are visualized using a bubble chart, facilitating the material selection process based on the defined criteria.The findings indicate that Titanium Alloy (Ti-6Al-4V) is the best candidate for landing gear applications due to its optimal combination of mechanical properties, durability, and low density. Meanwhile, Steel Alloy and Nickel-Based Superalloy demonstrate superior performance in certain parameters, such as tensile strength and maximum service temperature. CFRP also offers advantages in cost-to-performance efficiency, but its mechanical properties are not yet comparable to Titanium Alloy. In conclusion, Titanium Alloy (Ti-6Al-4V) emerges as the best choice to meet the specific requirements of aircraft landing gear applications. employees.
