Rotaring bending fatigue testing machine
MetadataShow full item record
The purpose of this research was to construct the rotating bending fatigue testing machine for metal material to find out the built-in machine performance and compare it with machines that meet international standards. The machine built into a compact machine using weight knob for a heavy load in testing. It can test the force range 50-300 Newton (N), the motor is a 1 HP transmitter with a speed of 2,800 rpm. Start by pressing the Start button to release the weight that sends power to the workpiece and attend a sensor counting is available to detect the lack of testing material. For the efficiency performance of the machine uses 10 piece steel shafts, diameter of 8 mm according to the standard of the material fatigue tester by independent end bend rotation. For testing to compare with the test international standard machine also uses 10 piece steel shafts, using force 150 N. For the analysis to test statistical hypotheses with the Minitab computer program at the significance level of 0.05, it was found that the values obtained from be made the rotating bending fatigue testing machine for metal material, there is no difference with standard machines from statistically significant. All values are within the set limits. In conclusion, the machine was created to be as effective as the international standard machine.
