Abstract: (302 Views)
The engine mounting bracket is connected to the engine on one side and to the car body on the other side. The engine mounting bracket should be designed in such a way to prevent the transmission of vibrations from the body to the engine and vice versa. In addition, one of the tasks of the engine mounting bracket is to bear the weight of the engine and the dynamic and vibrational loads caused by the movement of the car on the road. The engine mounting bracket are generally designed in such a way that they have sufficient fatigue life in a defined range of cyclic forces and fail in the range of high forces caused by an accident in order to minimize the level of damage to the vehicle and passengers. This research will investigate the effect of manufacturing parameters on the fatigue behavior of the aluminum engine mounting bracket. High-cycle fatigue test was taken from the prototypes and based on the results of this test, the prototype was considered unsafe. Therefore, in order to improve the produced part, by removing the factors that cause weakness in the part and strengthening the area in front of the engine mounting bracket, the secondary sample of the engine mounting bracket was produced, but due to the high costs of re-fatigue testing, radiographic test was done of the reinforced areas before testing. Then, fatigue test was taken from the secondary sample. The test results of the modified sample were within the acceptable range.
