PADUAN VARIASI PUTARAN 0, 250, 550 RPM CENTRIFUGAL CASTING SIFAT FATIK PADUAN A 356 UNTUK VELG SEPEDA MOTOR
Abstract: The destination of
this research was to determine the effect of rotational speed on the
characteristics of fatigue in centrifugal casting alloy A356 aluminum alloy
two-wheeled vehicle with a low round and 350 RPM and 550 RPM middle rounds. The
casting in this research using a centrifugal casting method. The material used
is a cast aluminum alloy A356. Variations rounds used in centrifugal casting is
350 and 550 RPM. Casting process carried out by pre-heating the mold 2500oC,
7500oC casting temperature and with the addition of titanium boron grain
refiner 12:08%. Results foundry then made specimen for rotary bending fatigue
test in accordance with JIS Z 2274 standard 1. The examination has been done is
the rotary bending fatigue test. The examination results showed that the wheels
with a round 0 RPM produces a voltage amplitude relationship with the number of
cycles σa = 350 RPM rotation have a relationship with the voltage amplitude and
at 550 RPM rotation have a relationship with the voltage amplitude.
