Wheel Balancing Lab Report

Introduction:

The process in which the rotating disturbing masses are equalized by using one or more balancing mass in same or different planes at specified angle and radius as per requirement. Why System Becomes Unbalanced?

Balancing is very important in vibration analysis. If a disturbing mass is present in a rotating body, it will cause a centrifugal force acting outward form center of rotation. Therefore, it will cause fluctuations in body. Reason of fluctuations is that a centrifugal force is action on one side of rotating body while there is no force on other side to balance it so a net displacement is produced in direction of this force. Because body is rotating, so it causes periodic displacement in each direction so it causes vibrations.

the purpose is again to have the smooth running of vehicle. While Balancing the wheel we actually put the wheels on a machine i.e. wheel balancer which centers the wheel and spins it in order to determine the amount as well as the position or location where the weights should go to have balancing. What the wheel balancing strategy

It is not true that whatever the problem in the wheels are here, the only solution is to balance them. Actually, balancing of the wheel will deal with only those problems which are not physical in nature e.g. because of the wear and tear, if the mass or weight over certain portion has gone away leading to unbalancing, this would be handled by the wheel balancing but if the wheels are bent too much and this is the cause of vibrations in the system then wheel balancing will not do good in this regard. Generally speaking, wheel balancing simply compensates the vibrations caused by the weight differences. Why The Wheels Are Unbalanced?

There are certain reasons leading to the unbalancing of the wheels e.g.: One of the possible reasons is the wear and tear of tire with use. Therefore, if one wants to have maximum life of automobile without serious shocks or any sort of trouble, rebalancing of the wheels for at least once throughout the life of the tires will probably extend the specified lifetime. Another possible cause of unbalancing is when the tires are get punctured. When they are recovered, often the weight on that certain portion exceeds from rest of the wheel tire assemble which causes the unbalancing of the wheels. When this is the situation the dynamic forces are produced which certainly intensify the load on the bearings as well as increase the stress on a number of members of the
