Analisis Kekuatan Struktur Komposit Sandwich Pada Main Landing Gear UAV

Abstract

Tricycle landing gear adalah konfigurasi landing gear pada pesawat dengan nose landing dan main landing. Analisis kekuatan komposit sandwich dengan beban impact bertujuan mengetauhi kekuatan maksimal yang dapat ditahan oleh sandwich dengan beberapa lapisan lamina yang disusun dengan variasi arah orientasi serat untuk mendapatkan kekakuan,mengetahui jenis kerusakan akibat pembebanan yang berlebihan. Optimisasi arah serat dilakukan untuk memperoleh variasi arah serat yang optimal dalam menerima pembebanan, didapatkan arah serat optimal yakni [(0)(45)(-45)(90)(0)]s dengan nilai Tsai-hill yang signifikan dari 0.091052752 menjadi 0.057597845 setelah optimisasi. Simulasi pembebanan impact dengan variasi kecepatan vertikal 2 m/s, 3 m/s 4 m/s, 6 m/s, 8 m/s, 10 m/s, 12 m/s, 15 m/s dengan menggunakan metode elemen hingga dengan memanfaatkan software Abaqus CAE pada model main landing gear dan melakukan pengujian hingga didapatkan besar displacement, stress dan strain. Dengan dilakukakannya pengujian maka diperoleh bahwa struktur main landing gear mampu menahan kecepatan landing hingga 12 m/s dengan besar tegangan sumbu X (S11) 447,118 Mpa, tegangan sumbu Y (S22) 30,4995 Mpa, tegangan geser sebesar 26,2218 Mpa dengan besar displacement 11,9461 mm dan nilai tsai-hill sebesar 0,5920. Pada kecepatan landing 15 m/s struktur landing gear mengalami kegagalan dengan nilai tsai-hill yang telah melewati indeks kegagalan 1, dengan besar tegangan sumbu X (S11) 477,556 mpa, tegangan sumbu Y (S22) 44,4075 Mpa, tegangan geser sebesar 35,2047 Mpa dengan besar displacement sebesar 15,8297 mm dan nilai tsai-hill sebesar 1,1336 dimana kecepatan landing ini struktur landing gear mengalami kegagalan ditandai dengan nilai tsai-hill yang telah melampui nilai indeks kegagalan 1. Kata kunci: Main Landing Gear, UAV, Drop Impact, Komposit Sandwich.
