Overview about the
topic
As we all know, a wheel consists of a wheel rim and a tire. Because this is the part
that bears all the weight on the car. If the wheel is of poor quality or is deformed
too much due to the operation of the car, it will cause a lot of dangers on the
road. Severe can be very life or injury related.

CHAPTER 1: OVERVIEW
Introduce of the product; Product Specifications


The rim is the "outer
edge of a wheel, holding
the tire." It makes up the
outer circular design of
the wheel on which the
inside edge of the tire is
mounted on vehicles such

as automobiles.

CHAPTER 5:
CONCLUSION


Conclution
Conclusion sums up what have been analysis above so as to give some
information about the strain, flexibility, safety factor and its
deformation.
In this report, many analysies have been gone through and we have
come out with some conclusions below:
• It’s very important to consider about the force applied on the wheels
rim. Because when the force is applied, it will lead to change many
things such as: structural error, equivalent stress, total deformation and
safety factor. If everything isn’t simulated and calculated carefully, it will
dangerous when we use transportation.
• Some problems about the wheels rim have been solved in this report.

Through analysis:
-We know how to choose the element size in mesh and decide which
one is the best for every purpose.
-How mesh and force impact structural error, safety factor,
equivalent stress and total deformation
-Which value of force can be applied to the wheels rim, and with
every force, the wheels rim will change in which way.
