In A123 Systems, CAE/FEA tools are widely used to improve the efficiency of the design on battery packs and modules. A123 engineers utilize Altair’s HyperWork Suite for structural FEA including linear and nonlinear statics analysis, modal frequency and random vibration analysis, as well as nonlinear dynamic analysis such as mechanical shock and drop test analysis.
Two examples are presented in this presentation. The first example is a systematic approach to simplify and accurately model complex prismatic battery modules for vibration FEA. The second example presented is an approach to utilize Altair’s partner program DesignLife to conduct durability analysis.
