Take three points as shown in Figure 1 to study the changes of stress, strain and temperature with time in the forging process of driving spiral bevel gear blank. P1 is a point at the top step, P2 is a point in the middle, and P3 is a point at the tail.
The time-dependent curves of equivalent stress, strain and temperature at the three points obtained from post-processing are shown in Fig. 2, Fig. 3 and Fig. 4.
