| 2 | Behavior of an improved pseudo -viscous frictional damper (IPVFD) was studied by testing and numerical analysis. | |
| 3 | Based on the semi-active control theory, a new type clearance viscous damper is presented in this paper. | |
| 4 | When this formula is used to correct the error, the effect is very clear. | |
| 5 | Yet even at great depth, the mantle remains an exceedingly viscous fluid, flowing ever so slowly even in response to extreme pressures. |
