Modal Analysis Optimization and Test Verification of A Battery Pack |
| |
| Abstract: | According to the requirement of safety performance of battery pack, vibration test should be carried out to verify the reliability of structure and performance of battery pack. The vibration test of a battery pack shows that the resonance phenomenon occurs near the module and the fixed bracket of the module at 20 to 24HZ. Based on this problem, the structural modal analysis of the battery is carried out and the structure is adjusted to find a solution. |
