METHOD AND APPARATUS FOR SUSPENSION DAMPING INCLUDING NEGATIVE STIFFNESS |
| 摘要 |
A suspension assembly between a sprung element and an unsprung element includes load-carrying spring arranged in parallel with a negative stiffness element between the sprung element and the unsprung element. The spring is configured with a positive spring rate to support a static load of the sprung element. The negative stiffness element is configured with a negative spring rate and to exert a force opposing the spring rate of the spring. The negative spring rate has a magnitude that cancels the positive spring rate at a zero deflection point of the suspension assembly. |

1. A suspension assembly between a sprung element and an unsprung element, comprising:
a load-carrying spring arranged in parallel with a negative stiffness element between the sprung element and the unsprung element; the spring configured with a positive spring rate to support a static load of the sprung element; and the negative stiffness element configured with a negative spring rate and to exert a force opposing the spring rate of the spring, said negative spring rate having a magnitude that cancels the positive spring rate at a zero deflection point of the suspension assembly. |
