The Mode and Calculation of Blast Vibration Momentary Input Energy Based on Hilbert-Huang Transform
Blasting vibration on the surrounding building (structure) in real terms is the impact of energy transfer. Energy methods reflect the shock intensity, the characteristics of the spectrum, especially the combined effects of damage to the building from duration. The concept of Momentary Input Energy embodied the common role of vibration velocity and frequency, and structures damage is mainly depended on the maximum Momentary Input Energy of blast vibration wave. In this paper, from the viewpoint of the blast vibration energy damage mechanism, based on energy reaction equation, combined with the concept of Momentary Input Energy, on the basis of Hilbert-Huang Transform, the author creatively put up the mode of Momentary Input Energy of blast vibration and calculation method of the maximum Momentary Input Energy.
