Abstract
Ban merupakan bagian dari kendaraan yang berperan
penting dalam kenyamanan dan keamanan dalam proses
berkendara. Sebagai bentuk dari perkembangan teknologi
kendaraan, ban airless dihadirkan untuk mengatasi permasalahan
yang ada pada ban radial. Namun, ban airless belum bisa
diproduksi secara massal karena masih dalam tahap penelitian,
salah satunya terkait ukuran fitting ban airless pada velg. Apabila
fitting ban pada velg terlalu longgar, velg tidak mampu
mentransmisikan gaya dan torsi pada ban sehingga terjadi slip.
Apabila fitting ban pada velg terlalu rapat, pemasangan ban ke
velg akan lebih sulit serta memungkinkan timbulnya tegangan
berlebih yang mengakibatkan ban mengalami kerusakan (crack).
Maka dari itu, perlu dilakukan analisis interference fit antara ban
airless dengan velg.
Pada penelitian ini dilakukan analisis interference fitting
ban airless pada velg ban sepeda motor menggunakan software
ANSYS Workbench 18.1: Static Structural. Tahapan penelitian ini
dimulai dengan membuat desain assembly ban airless dan velg
menggunakan SOLIDWORKS 2018. Desain ban airless mengacu
pada penelitian dari Agus Sigit Pramono et al. pada tahun 2019
sedangkan desain velg mengacu pada ukuran velg yang digunakan
untuk sepeda motor matic. Kemudian, desain tersebut
disimulasikan menggunakan software ANSYS Workbench 18.1
dengan metode static structural. Simulasi dilakukan dengan
variasi fitting allowance dari ukuran 0,2 mm hingga 2 mm denganx
perbedaan ukuran tiap simulasinya sebesar 0,2 mm. Hasil yang
diamati yaitu total deformation, von-mises stress, dan contact
pressure. Dari hasil contact pressure tersebut, dengan rumus
perhitungan yang ada didapatkan nilai torsi akibat interference fit.
Nilai torsi ini kemudian dibandingkan dengan torsi roda sepeda
motor, yaitu sebesar 290822 N.mm untuk mengetahui apakah
terjadi slip pada ban airless terhadap velg.
Hasil penelitian menunjukkan bahwa nilai tegangan
terkecil didapatkan ketika fitting allowance 0,2 mm yaitu sebesar
0,0462 MPa sedangkan nilai tegangan terbesar didapatkan ketika
fitting allowance 2 mm yaitu sbesar 0,5691 MPa. Selain itu,
didapatkan bahwa ukuran minimum fitting ban airless pada velg
agar menghasilkan nilai torsi yang sama dengan nilai torsi roda
sehingga tidak terjadi slip pada ban airless terhadap velg yaitu
sebesar 0,7216 mm

Tyres are part of vehicle that plays an important role in
comfort and safety in the driving process. As a form of vehicle
technology developments, airless tires are presented to overcome
the problems that exist in radial tires. However, airless tires have
not been mass-produced because they are still in the research
phase, one of them is related to the size of airless tire fittings on
the rim. When the tire fittings on the rim are too loose, the wheels
are not able to transmit the force and torque of the tires so that the
slip occurs. If the tire fittings on the rim are too tightly, the
mounting of the tire to the rim will be more difficult and allow the
occurance excess stress resulting in the tire experiencing damage
(crack). Therefore, an interference fit analysis is required using the
finite element method.
In this research, interference fitting analysis of airless tire
on motorcycle tire rim was conducted using ANSYS Workbench
18.1: Static Structural software. The phase of the research began
with the design of airless tire and the rim assembly using
SOLIDWORKS 2018. The airless tire design refers to the research
of Agus Sigit Pramono et al. in 2019 while the rim design refers to
the size of the rim used for matic motorcycle. Then, the design was
simulated using ANSYS Workbench 18.1 software with static
structural method. The simulation was done with a variation of the
fitting allowances from 0.2 mm to 2 mm with the difference of each
simulation of 0.2 mm. The results observed were total deformation,
von-mises stress, and contact pressure. From the result of thexii
contact pressure, with the existing calculation formula, torque
value due to interference fit obtained. This torque value was then
compared with the wheel torque, which is 290822 N.mm to
determine wether there is an airless tire slip against the rim.
The result shows that the smallest stress value is obtained
with the fitting allowance of 0.2 mm that is 0.0462 MPa while the
largest stress value is obtained with the fitting allowance of 2 mm
that is 0.5691 MPa. In addition, it is obtained that the minimum
size of the airless tire fitting in the rim to produce the same torque
value as the wheel torque so that there is no slip on the airless tire
against the rim is 0.7216 mm
