Abstract :
The UAV Sprayer AMF?16 IF aircraft is designed with a mission of
watering and spraying plants with a carrying capacity of 3 kg. This aircraft is also
made for helping agricultural activities can be more effective and efficient. It is
categorized as a rotary wing with a total of 4 motors and can take?off landing in
narrow runway conditions. For this reason, this study discusses the design and
analysis of structural strength for UAV Sprayer AMF?16 IF.
The process begins by calculating the weight sizing and creating the
geometry. Then proceed to the modeling process using CATIA V5R21 software. The
finished modeling is imported into the ANSYS 17.1 software for structural strength
analysis. Structure loading is carried out under 2 conditions, namely static load
and vertical take?off. The results of the analysis to obtain the maximum stress value
which is useful for knowing the failure criteria value and the margin of safety.
The results of this studys show that the UAV Sprayer AMF?16 IF aircraft
has an overall weight of 7.806 kg. The maximum stress value that occurs in the
aircraft structure is 2,0129x107 Pa (static load) and 1,4919x107 Pa (vertical take?
off). Hence, the highest value of failure criteria is 1,1171x10-2
(static load) and
3,6362x10-2
(vertical take?off). while the highest value is margin of safety of
15,3258 (static load) and 16,6383 (vertical take?off).
