Apart
from the above-mentioned parts, the vehicle manufacturer holds some parts of powertrain components which they
exclude or include from individual powertrain warranties as they find them fit
and better. This can be hubs or wheel bearings, the exhaust manifolds, axle
shafts and much more.
Influences stress
You
can focus on the major components of it and understand how the powertrain warranty
applies to them. The powertrain components as the gearboxes and engines usually have bolted contact
surfaces, which are high in number. This non-linear interaction between the
parts largely influences stresses under its vibration behavior and loads.
You
can take the example of the transfer case which depicts stress distribution on
housing flange in the assembled state. With the inclusion of such housing as
the flexible structure, it offers the dynamic simulation of the powertrain.
Leak tightness is analyzed
The
time-based on the stresses within the housing and the contact stresses can also
be easily evaluated. Based on such results, housing durability and leak
tightness can also be analyzed well. When you will have a look at the
powertrain components, you will find a torsional damper which is bolted on the crankshaft, is dynamically loaded too.
There
are certain benefits of using powertrain components which include,
·
The analysis of the
leak tightness in bolted housing
·
The evaluation of
fretting corrosion because of dynamic loads
·
The evaluation of
complete rpm range for including them in the resonance effects
In
the areas where the pressure is reduced during the peak load, the fretting
corrosion is also observed.
