摘要
采用有限元方法研究了螺栓孔布置方式和螺栓孔数量对无人机主起落架架强度的影响。使用Autodesk Inventor Professional 2017软件进行线性静态分析。主起落架架采用5083铝合金。螺栓孔的排列和数量为3个(串联)、3个(之字形)、4个(串联)、4个(之字形)、5个(串联)、5个(之字形)。仿真结果表明:3个螺栓(串联)、3个螺栓(之字形)、4个螺栓(串联)、4个螺栓(之字形)、5个螺栓(串联)、5个螺栓(之字形)布置的安全系数分别为3.498、3.325、3.843、3.793、3.401、3.338。
PENGARUH SUSUNAN DAN JUMLAH LUBANG BAUT TERHADAP KEKUATAN RANGKA MAIN LANDING GEAR UNTUK PESAWAT UAV
This study examined the effect of the arrangement and number of bolt holes on the strength of the main landing gear frame for UAV aircraft using the finite element method. Linear static analysis was carried out using Autodesk Inventor Professional 2017 software. Main landing gear frame using Aluminum alloy 5083. Variable arrangement and number of bolt holes were 3 bolts (series), 3 bolts (zigzags), 4 bolts (series), 4 bolts (zigzags) ), 5 bolts (series), and 5 bolts (zigzags). The simulation results show that the safety factor is for the arrangement and the number of bolts 3 bolts (series), 3 bolts (zigzags), 4 bolts (series), 4 bolts (zigzags), 5 bolts (series), and 5 bolts (zigzags) were 3.498, 3.325, 3.843, 3.793, 3.401, and 3.338.
