description |
The shot peening process is used mainly to harden the surface and increases the fatigue life of the rotating parts. This cold treatment will change the designed natural frequency of the part and change the vibration characteristics. Especially when these parts are driven by a high-speed velocity. This research investigates the behavior of the vibrations after a superficial treatment done by shot peening. An experimental test rig was manufactured, and different industrial applications and geometries have been tested and treated by the shot peening process. Three important commonly used industrial applications are selected to study and investigate its vibration characteristic after shot peening treatment namely connecting rod, crankshaft, and supercharger shaft for a (3Kv) generator. Vibration parameters such as acceleration velocity and displacement for specific time duration were recorded and analyzed also the natural frequency and first six mode shape. The fundamental increases after shot peening and the percentage of increase in natural frequency for the crankshaft, connecting rod, and supercharger shaft are (26%), (32%), and (20%) respectively where. For comparison reasons, different numerical finite element models for the connecting rod, crankshaft, and superchargers shaft are suggested and implemented in ANSYS 15. Good accuracy was achieved between numerical models and experimental measurements.
