Abstract
In this paper, two different methods for the simulation of shock loads for high-voltage batteries are investigated. First, a test body is designed that allows the excitation of different eigenfrequencies, and dynamic measurements are performed on an electrodynamic shaker. Thereupon a simple simulation method based on a single-mass oscillator using MATLAB for the integration of motion equations is introduced. Finally, the test body is analyzed using FEM simulation. The results show that there is a good agreement between experiment and FEM simulation comparing absolute values of maximum acceleration response. The use of single-mass oscillators is imprecise for the determination of absolute values. When comparing normalized acceleration response, a good agreement is achieved for both methods.
