Study of the Influences of Transient Crack Propagation in a Pinion on Time-Varying Mesh Stiffness
Table 4
Mesh stiffness reduction caused by TPOC (with the model of step function but different lengths) in different deterioration levels.
| Deterioration levels of crack before TP | TP model | Stiffness value ( N/m) | Stiffness reduction caused by TPOC ( N/m) |
