| description | A finite element simulation model is established for the gearbox body of 120B metro vehicle model in China. The fatigue strength, static strength and safe nose strength of the aluminum alloy and the nodular cast iron gearbox are calculated by the finite element method; the results show that the maximum equivalent stress of the aluminum alloy case is larger than that of the nodular cast iron case, and the maximum difference ratio is 36.3%. The static strength and type test of aluminum alloy and nodular cast iron box are compared. The results show that the maximum stress of aluminum alloy case is greater than that of ductile iron, and the difference ratio is 8.3%, the maximum sound power and vibration value of the aluminum alloy case are greater than that of the nodular cast iron case, but the average bearing temperature decreases by about 10 ℃. Although the strength of the aluminum alloy case is weaker than that of the nodular cast iron case, the overall factor of safety of the aluminum alloy case is higher than that of the nodular cast iron case, and can still meet the service life of 33 years or 9.6 million km requirements. In this paper, the applicability of aluminum alloy box is analyzed. The results show that both aluminum ductile iron and aluminum alloy can be used in metro gear box, and can be based on the specific requirements of the vehicle preference selection in the design. |
