Abstract

Comfort and safety in the operation of an unmanned aerial vehicle (drone) are crucial elements within its flight system. To achieve these conditions, a deep understanding of several parameters is required, such as maximum load limits, stress, strain, displacement, and safety factor on the materials used. The aim of this research is to analyze the strength of suitable plastic and aluminum materials for a quadcopter drone, as well as to assess the durability of the drone frame material using Finite Element Analysis (FEA). The analysis process begins with simulation preparation using FEA. A 2D and 3D drone frame model is created using Solidworks software, followed by material selection (Aluminium Alloy 2018 and Plastic PA type 6) involving characteristics of the drone frame. The pre-processing process includes geometry modeling, material selection, element choice, and mesh creation. The FEA processing involves setting boundary conditions, solving equations, and analyzing results. The strength type examined in this research is the fixed geometry model. The subsequent steps involve analyzing von Mises stress, stress, strain, displacement, and safety factor under two load variations: 1 kg and 3 kg.The results of this research for Alloy 2018 material are as follows: The maximum stress under a 1 kg load is 1,294,695 N/m², while under a 3 kg load, it is 1,690,748 N/m². For Plastic PA type 6 material, the maximum stress under a 1 kg load is 1,294,027 N/m², and under a 3 kg load, it is 3,882,082 N/m². The minimum stress for both materials is 0 N/m² for all loads. The maximum displacement for Alloy 2018 material is 0.019 - 0.025 mm under a 1 kg load and is not provided for a 3 kg load. For Plastic PA type 6 material, the maximum displacement under a 1 kg load is 0.532 mm, and under a 3 kg load, it is 1.595 mm. The minimum displacement for both materials is 0.000 mm for all loads. The maximum strain for Alloy 2018 material is 0.000011 under a 1 kg load and 0.000014 under a 3 kg load. For Plastic PA type 6 material, the maximum strain under a 1 kg load is 0.000303, and under a 3 kg load, it is max 0.000908. The minimum strain for both materials is 0.000000 for all loads. In terms of safety factor, Aluminum Alloy 2018 material has a safety factor of 6,797,097 N/m² under a 1 kg load and 8,876,430 N/m² under a 3 kg load. For Plastic PA type 6 material, the safety factor is 6,793,641 N/m² under a 1 kg load and 20,380,983 N/m² under a 3 kg load.
