Principles Of Dynamometer Operation

Submitted by: Avi Eshkol

The very concept of dynamometer is always attached with technology. Therefore it appears a little bit of tough for those who do not have any idea about it. So if a person wants to know about the ins and outs about the main principles of dynamometer operation, he needs to collate some basic information about it.

Actually there is a basic difference between a dynamometer and a voltmeter. True, both of them are measuring tools and both have to execute some functions in their own arena. If one can understand this, it will be easy for him to grab the other information easily and more accurately. Unlike the voltmeter a dynamometer is consisted with a pliable ring made of metal, which uses to bend whenever something tried to bend it. Its bending condition depends on the force that will be applied on it.

Setting up an engine would be incomplete with out using any automotive Dynamometer. The proper function of an engine is largely dependent on the function of a dynamometer. Therefore it has become imperative to have a dynamometer with a new motor to enhance its functionality. Adding up a gas analyzer with a dynamometer would be a perfect idea as this will achieve one to get a better result. This addiction will help one immensely to enhance the capability.

Transmission Dynamometers and absorption dynamometers are variant form of Power-measuring dynamometers. This kind of dynamometer uses a device that is largely dependent on the concept of measuring torque. A flexible or a special kind of torque meter is generally infixed in the shaft. Actually the burden which a motor or machine is carrying, is responsible for producing a torque.

The torque produced by a transmission dynamometer is starkly different from a torque that is produced by absorption dynamometers. Absorption dynamometers produced that torque by using fluid friction, electromagnetic induction or mechanical friction.

Using the break blocks can do developing a mechanical friction on the edges of revolving pulley. Then the break blocks are compressed against the wheels by fastening the bolts. This action continued until the friction torque FR balances. A water break uses another system. It develops resistance by the help of the rover flow. This water flow has been circulated between a stationary shell and a rotating impeller. At that particular time, the dynamometer produces direct current electricity, which is also known as the eddy current.

The concept of Torque is important enough to be clarified. Actually it is the direct result of the load of the spring or weight. Its distance from the axis of rotation is also responsible for determining the torque. Actually Dynamometers are used to calculate the production of torque by an engine. This information is needed to determine the overall performance of an engine.

All the information related to this issue is demonstrated on a graph, which can be interpreted easily. By using this graph the engineers decipher the essential information that they need to find out by using the dynamometer.
