In this paper, response surface method is used to find out the fatigue life equation by taking load and dimensions of the wheel as variables. The natural frequency is taken as a factor for fatigue life. An ANOVA analysis is carried out to formulate the natural frequency function. An objective function has been formulated to minimise the mass of railway wheel considering the strength and geometrical constraints of inner hub-hole, hub-web interface and hub-rim interface.

Abstract


In this paper, response surface method is used to find out the fatigue life equation by taking load and dimensions of the wheel as variables. The natural frequency is taken as a factor for fatigue life. An ANOVA analysis is carried out to formulate the natural frequency function. An objective function has been formulated to minimise the mass of railway wheel considering the strength and geometrical constraints of inner hub-hole, hub-web interface and hub-rim interface.
