In this research, a study of solution to the problems of transmission in
wind turbines, where the electronic appliances and gearboxes
components responsible for much of the wind turbine problems as they
increase the cost of operation and maintenan
ce of wind turbines and
here comes the role of variable transport systems ratios, which is a
solution more efficient than in fixed proportions regimes where create
a dynamic model of the turbine wind using the aerodynamic properties
of the blade wind and calculate torque when the wind changing speeds
values and this for each of the wind turbine with proportions variable
order and fixed ratio using MATLAB software and after study shows
that energy production is slightly higher and more importantly, so it is
possible to say that the CVT system is a candidate to be the subject of
research for future developments of the technology of wind turbines.
In this research, gearbox has been designed according to the two rows
planetary and several directly rows to rotate the four-roof building in
Homs city while maintaining the relative rotation between the floors,
and the study of the steel core and
wholesale construction of the
building to calculate the required engine power to rotate each floor
privately and the study of required bearings, gears and hubs, and then
study the effect of rotate the building at energy saving.
The use of modern methodologies and techniques a new approach to evaluate the
process of engineering design in the industry pay to use in evaluating the speed in large
cans mechanisms design.
The gearbox that is designed for big vehicles for off-r
oad driving conditions need
portal axle which installed between the wheel and the axle shaft to give higher ground
clearance to the vehicle.
The modeling and simulation of spur gear which contacted with portal axle is
important to predict the actual motion behavior, but it's so complicated to study.
In this study, it'll analysis the portal axle by using finite element method (FEM),
modal analysis will simulated on three different combinations of gear train system, the
three gear trains being analyzed are: gear train without idler gear, one idler gear and two
idler gears.
FEM static stress analysis will also simulated on three different gear train to study
the gear teeth bending stress and contact stress behavior of the gear trains in different
angular positions from °0 to °18 degree.
