Effective Fatigue Evaluation on Rubber Mounts for Rail Vehicles

Figure 5

The profile and the orientation of the effective stress with the failed profile at the bottom interface of the whole buffer. (a) The effective stress profile of the bottom interface of the buffer. (b) The zoomed area of the hot spot at the bottom interface of the buffer. (c) The effective stress direction at the hot spot of the bottom interface in the YOZ plane (−16.4° from Z. (d) The effective stress direction at the hot spot of the bottom interface in the XOY plane (88.9° from X). (e) The effective stress direction at the hot spot of the bottom interface in the XOZ plane (−89.7° from X). (f) The hot spots at the bottom interface of the whole buffer. (g) The failed bottom interface of the whole buffer (debonding underneath).
