Dynamic Simulation Analysis on Axle Spline of High-Speed Train Gauge-Change System

Figure 24

Phase II: Real-time stress distribution of the contact area on axle spline surface under identical loading case, at φ = 0.01°, 0.02° and 0.04°. (a) Real-time stress status with circumferential misalignment φ = 0.01° under 0.5 m/s2 driving rate, #10 tooth. (b) Real-time stress status with circumferential misalignment φ = 0.02° under 0.5 m/s2 driving rate, #10 tooth. (c) Real-time stress status with circumferential misalignment φ = 0.04° under 0.5 m/s2 driving rate, #10 tooth.
