Energy storage system vibration resistance

Does random vibration excitation affect the fatigue life of a power battery?

Based on Palmgren-Miner damage theory, they conducted simulation analysis on the fatigue life of the power battery under random vibration excitation. They proposed a method for analyzing the random vibration fatigue of power battery box structures.

Does energy storage Supercapacitor box experience resonance?

The supercapacitor box will not experience resonance. The fatigue characteristics within the frequency domain under random vibrations defined by ASDs is analyzed. The maximum fatigue damage of the energy storage supercapacitor box is 6.24 × 10 − 6. The number of fatigue cycles is on an order of 10 5.

Can random vibrations cause fatigue damage?

Long term exposure to such random vibrations could lead to fatigue damage. The previous studies mainly focus on the simulation of fatigue characteristics of battery packs, and there are relatively a few literature on simulation of the fatigue performance of energy storage supercapacitor box structures under random vibration loads.

What are the fatigue characteristics of energy storage Supercapacitor box?

The fatigue characteristics within the frequency domain under random vibrations defined by ASDs is analyzed. The maximum fatigue damage of the energy storage supercapacitor box is 6.24 × 10 − 6. The number of fatigue cycles is on an order of 10 5. Then the energy storage supercapacitor box is manufactured using lightweight aluminum alloy 6063-T5.

Why is random vibration fatigue analysis important for a supercapacitor box?

Therefore, fatigue performance analysis under random vibration is of great significance for the design and life prediction of the supercapacitor box. The methods for structural random vibration fatigue researches primarily consist of two approaches: the time-domain method and the frequency-domain method.

What are the methods for structural random vibration fatigue research?

The methods for structural random vibration fatigue researches primarily consist of two approaches: the time-domain method and the frequency-domain method. The time-domain method demands high-quality signals, necessitating a long duration of the signal, extensive computational resources, and longer calculation times.
