This lesson covers the importance of vibration in mechanical design, discussing various vibration modes, model analysis, and frequency response. The lesson also compares different standards used in India, such as AIS 048 and AIS 156. It emphasizes that a battery pack design should be safe, cost-effective, lightweight, and highly reliable. For instance, every gram reduction in weight helps improve the range of the battery pack. It also covers how to simulate harmonic vibration analysis to find mode of frequencies and shapes of side plate.
