Özet:

 


In
this study, thermodynamic
and kinematic analyses of bell crank, slider crank, rhombic and scotch yoke drive mechanisms were
performed for a beta type Stirling engine with a swept volume of 365 cm3.
The kinematic analyses of Stirling engines with
these different drive mechanisms were investigated by using the MSC Adams
program, and the pressure-volume variations depending on the crankshaft angle
were determined by using the isothermal analysis method. It was determined that compression and expansion volume values of
rhombic drive mechanism were close to each other, while compression volume
value was extremely higher than expansion volume value in other drive
mechanisms. For this reason, in this research conducted with working fluid of
equal amount (m=0.000716 kg), for all of drive mechanisms, it was determined
that engine with rhombic drive mechanism generates 19.2% net work more than the
other drive mechanism. The masses of working fluid used in 1 bar charge
pressure from engines with bell crank, slider crank, rhombic and scotch yoke
drive mechanism were 0.000716 kg, 0.000737 kg, 0.000536 kg and 0.000724 kg,
respectively. The net work amounts obtained as a result of the thermodynamic
analyses made for the 1 bar charge pressure value in bell crank, slider crank,
rhombic and scotch yoke drive mechanisms are 12.85 J, 12.44 J, 11.61 J and
13.05 J, respectively. In this research conducted with working fluid in the
same charge pressure, it was determined that 10.8% less net work was obtained
from engine with rhombic drive mechanism. Since all the changes of the volume
in the bell crank, slider crank and scotch
yoke drive mechanisms are very close to each other, the net work performance
values obtained with the equal amount of working fluid and the same charge
pressure values are also very close to each other.
