Fatigue and Modal analysis of ER۲۴ locomotive bogie for manufacturing purpose

Because of the importance of life-cycle and operational security of the locomotive’s chassis called bogie, a static analysis of wheel and axle of ER۲۴ locomotive’s bogie based on typical standards using different loads is required and conducted; including changes in axle load and acceleration, and then estimated the overall fatigue life of both wheel and axle. Points of interest in estimating fatigue life of wheel are: ۱. Effect of train’s speed on fatigue life and ۲. Effect of axle load on fatigue life. These factors were calculated using ANSYS software. In the end, a Modal analysis of the structure which informs about its natural frequencies and structural properties is conducted.
