| 總結: | The growth of the aircraft industry always increases from year to year, this includes the
increase in aircraft production. Airplanes have many crucial components including aircraft
wheel bolts. The bolt serves as a link between the wheel and the wheel plate. When an
airplane takes off and lands, the plane's wheels will experience shocks to support the plane.
In the same process, the aircraft wheel bolt will experience stress and strain to hold the
aircraft wheel and wheel plate. The stresses that pass through the tensile strength will cause
changes in dimensions and hardness of the aircraft wheel bolts. Therefore, it is necessary to
conduct further research on aircraft wheel bolts so that the changes that occur do not exceed
the capacity of the material. In this research, two types of samples will be taken, namely
samples before being used on airplane wheels and samples that have been used on airplane
wheels. Based on the two samples, the dimension changes and changes in the hardness of
the plane bolts will be measured. Bolts that have been used on aircraft wheels have increased
dimensions / deformation values at the depth of thread, root radius and angle of thread points
respectively by 1.4%; 2% and 3.4%. Bolts that have been used on aircraft experienced an
increase in hardness at points A, B, C by 6.1%; 13%; and 4.3%. There is no significant
change in the microstructure.
