Abstract: The purpose of this
research is to analyze the crank shaft mechanism theoretically with
trigonometry and complex number methods. Equation of velocity and acceleration
of these methods are taken the same and the difference of influnced
variables. The same variables are angle
position, angle velocity, and beam length
2 and linking
beam length 3.
The differences is
for complex number
analysis influenced by angle position, angle velocity and beam angle
acceleration 3. Based on used variable for
these methods, trigonometry
analysis can be applied
if crank shaft
angle velocity is
a constant. Calculation of
velocity and acceleration are based on
beam angle 2 change from 0o
- 360o with angle range 15o
counter clock watch (CCW), crank angle velocity 188.4 rad/s, length of
beam 2 (0.05 m, 0.075 m. 0.10 m) and length of beam 3 (0.3 m). The result of
trigonometry and complex number calculation
for variation of
beam lenght 2
is taken the
difference of velocity
and acceleration on piston. The difference percentages of
velocity are 8.25%, 12.76%, and 17.78 %
respectively and of acceleration are 0.50%, 2.34%, and 19.91 % respectively.
