3. The wheel hub is one of the crucial part of
wheel that include spokes at the center of most
wheels.
A hub assembly contains the wheel bearing ,
and the hub to mount the wheel to vehicle.
It is located between the brake rotors and axle.

Design of wheel should be based on stress
generated under consumer usage.
It is highly steered safety components which
must not fail under loading condition.
Main parameters for design is loading
condition , manufacturing process and material
behavior.
6. BY : AUTHOR S DHAR ,VOL 9,
Catastrophic failure of wheel hub occurred
during service.
Nature of crack was corner crack.
The initiation of crack is complex.
7. After studying the literature ,the failure of wheel
hub are due to the following reason:
1) lack of lubrication
2) overloading the vehicle
3) installing the nut either too tight or too loose
This all problem occur at the time of loading
condition.

9. The bolt pattern is determined by the number
of bolts on the wheel hub.
Selection of material strong enough to hold the
weight of car
Type of lug nuts or bolts
Standard dimensions of wheel hub used in
cars.

17. After doing study on wheel hubs, we found
that the below mentioned materials are being
generally used for making of wheel hubs:
1. Aluminum (1060 alloy)
2. Steel (AISI 1035 steel)
3. Titanium
4. Composites (fiber and glass reinforced)
19. Titanium:
1. Advantages: Corrosion Resistant, High
Strength, Light Weight
2. Disadvantages: Machining and
Manufacturability, Cost and Availability
Composites:
1. Advantages: Mixed Properties, Light Weight
2. Disadvantages: Not Reliable, Developing
Technology
20. After studying their properties we found that
aluminum 1060 alloy and AISI 1035 steel are best
suitable out of four materials for making wheel
hub. Their properties are as follows:
AISI 1035 Steel:
36. Wheel hub has been designed in SOLID WORKS
software with the given parameters. The designed
assembly gives the stability during the rotation of
wheel
Based on analysis of stress distribution ,strain ,
fatigue analysis we found that aluminum 1060
alloy is better material for the wheel hub than
AISI 1035 steel.
The factor of safety for aluminum 1060 alloy and
AISI 1035 steel are 5.4 and 3.8 respectively. It
signifies that aluminum 1060 alloy is more reliable
than AISI 1035 steel
