| ln order to improve the vibration reduction performance of the traditional impact damper on the low frequency
mechanical vibration, a new type of elastic support impact damper was designed. Springs were added on the damper as
elastic support, and the energy exchange between the damper and the main system could be produced more fiercely,
which could further improve the effect of vibration reduction. The damping performance of the damper could be verified,
and the influence of the spring stiffness on the vibration characteristics could be analyzed , by comparing the experimental
results of the designed contrast experiments. The experimental results show that the vibration performance of the damper
is improved by using the springs, and the vibration on the low frequency vibration is better than other types of dampers.
The spring stiffness has a certain effect on the performance of the damper, and the spring stiffness has the best value. |
