Fat Extraction Solution
....
The fatigue strength and design strength of components are determined in fatigue strength tests or endurance tests. Moving components and machine parts are often exposed to periodically fluctuating loads. Even if the dynamic load is far below the static load capacity, this load can lead to fracture of the component after a long time because of material fatigue.
Features:
Automatically shuts down when the specimen fractures
Different specimens show the influence of notching and surface quality
Continuous Adjustment Of The Load Amplitude
Learning Objectives And Experiments:
Influence of different fillet radii and surface qualities on the fatigue strength
Fatigue strength of bars under reverse bending stress.
With this unit, it is possible to determine the basic principles of the fatigue strength testing.
On the panel's right side, it is placed the system with which the test specimen is loaded. This system is composed by a sping balance, which is joined to a threaded spindle by its upper end, while on its lower side, it is joined to an articulated guided system, in which it is held the right side of the test specimen. When turning the threaded spindle clockwise, we transmit a vertical force upwards to the test specimen.
On the lower panel of the unit, it is fixed an electric motor which axis is joined to an end of the test specimen (test bar) by means of a coupling. As well, this axis has a disc, which by means a device will count the number of turns of the motor.
In order to guarantee the force verticality, the system has two guides to avoid horizontal displacements during the transmission of stress.
The applied force can be directly measured using the spring balance.
On the upper panel, the unit control box is mounted, containing: the main (on/off) switch of the unit; the cycle counter that shows us the quantity of turns the motor's axis carries out; the motor's speed control that permits us increase or diminish the turning speed of the electric motor; the motor speed display that shows us the frequency in Hz, which is being transmitted to the motor at every moment; and the on/off switch of the electric motor.
Likewise, in order to assure the constant application of the load, besides of allowing the test specimen rotation on its axial axis, the system also permits the alignment of the coupling with the test specimen, due to the deformity suffered by bending.
Both the area where the test specimen is located and the motor axis outcome are covered with a protection cover, without it the unit does not work, since it is provided with a safety system to avoid accidents.
A USB cable (provided with the Trainer) connects the Trainer to the PCs USB Port. Mounted internally in the Troubleshooting Trainer, the micro-controller based fault board offers 21 different computer controlled faults.

The Fault Troubleshooting System Motor Control Troubleshooting Module consists of FaultPro software, PC-based fault control card, and fault module with a wide array of faults and individual plug-in connection cables, power supplies, and operation manual. Fault Pro software is a Windows-based software package that provides an online interface for student troubleshooting and a database for record keeping of student responses.
The Fault Troubleshooting System is unique because it can insert faults into electrical lines that carry full power to electric motors as well as control-level signals. This gives it the ability to create a more realistic troubleshooting environment for students. Fault Troubleshooting System Motor Control Troubleshooting Module adds to the model Motor Control Learning System to provide troubleshooting training via computer-based fault insertion. The Motor Control Troubleshooting Module also avoids damage to the equipment that is normally associated with manual fault insertion because it inserts the faults electronically. The Fault Troubleshooting System module gives teachers the ability to accomplish this in an effective manner because it can automatically insert a wide array of faults throughout the training system and record student responses in a computer database. Training equipment last longer and troubleshooting is safer for both the student and the teacher. Troubleshooting is one of the most important skills a student can learn. To do so requires intensive practice in a realistic setting and teacher analysis of each student's methods. With this system, the teacher can work freely in the classroom, analyzing each student's results and coaching them while other students are performing their troubleshooting exercises.
Features:
Insert faults into electrical lines that carry full power to electric motors
Provide troubleshooting training via computer-based fault insertion
Automatically records student responses into a database for easy scoring.
