By combining dynamic damping techniques in the upper section with lead shot in the lower section of our DP14 Damped Post, we have produced a mounting post that outperforms other designs. The post has a fundamental frequency of vibration of 16.8 ± 0.6 kHz.
The DP14 Damped Post performance is illustrated by comparing the time-domain impulse response of three different posts. Below, we see the typical "ringing" response of a solid post, along with the slightly better performance of a hollow post. The third plot shows the response of the highly damped DP14 post. Here we note that the impulse energy is quickly dissipated with the post ringing down in 50 ms.
All three of the plots shown above were measured by applying an impulse force to a post carrying a 1 lb. load attached to the top of the post. The displacement due to the applied impulse was monitored using an accelerometer.
