Rail grinding is an essential measure for the maintenance of railway infrastructure, and the machined surface integrity of rail material plays a crucial role in ensuring the safety, stability and service performance of the railway network. In this paper, an electroplated diamond grinding wheel was employed to re-profile the rail surface. Meanwhile,...
Rail grinding and wheel turning can effectively remove surface defects and unevenness, which is a crucial process for the safe and smooth operation of trains. Machined surface integrity of wheel/rail materials significantly influences their tribological property. In this study, firstly, the rail blocks were ground via a cylindrical grinding machine...
Rail milling plays an indispensable role to remove surface defects and irregularity in the railway maintenance industry. In this paper, an appropriate 2D orthogonal cutting model of rail milling process was established. Finite element simulations of rail milling were conducted in detail based on a modified Johnson-Cook constitutive model. The simul...
To guarantee the smooth operation of trains, rail grinding and wheel turning are necessary practices to remove surface defects. Surface integrity of machined wheel/rail materials is significant to affect their tribological performance. In this paper, firstly, the wheel specimens were turned by a CNC lathe and the rail specimens were ground by a cyl...
The machined surface integrity of heavy-haul freight wheel is one of the direct factors which affects the wheel’s service performance and life. Based on the wheel turning parameters, single-factor experiments on D840 wheel material under dry cutting condition were performed. The changing laws including the surface work hardening, surface microstruc...
Rail steel plays an indispensable role in the safety and stability of the railway system. Therefore, a suitable constitutive model is quite significant to understand the mechanical behavior of this material. Here, the compressive mechanical behavior of heat-treated U71Mn rail steel over a wide range of strain rates (0.001 s ⁻¹ –10000 s ⁻¹ ) and tem...
There are many possible trajectories between the given points in Euclidean geometry space for industrial robots. Under constraints of robotic kinematics or dynamics, the optimization of robotic running time is required. In this paper, a trajectory planning method of robot based on quantum genetic algorithm is proposed. Firstly, cubic B-spline funct...
A geometrical model for describing the ideal profile of a machined surface quantitatively is developed in this study. This model theoretically considers the elastic-plastic deformation in the third deformation zone, which is caused by the extruding and ploughing of the tool flank. The traditional geometrical model of a machined surface is modified...
A machined surface can be seen as a replica of the geometric outline of the cutting tool nose during the process of cylindrical turning, and the texture of the machined surface varies along with the tool wear. A new method of on-line turned surface monitoring is proposed in this paper by studying the grey value characteristics of the turned surface...
