摘要： 动力电池上盖模态直接影响到整车噪声、振动与声振粗糙度（NVH）性能及结构耐久 性能，为了提升动力电池上盖模态性能，通过形貌优化方法对上盖进行了结构优化。基于求 解器 MSC.Nastran 对动力电池上盖的模态进行了分析，根据分析结果，利用形貌优化法对重 点关注的第 1 阶模态进行了优化，通过改变上盖结构特征，使得上盖第 1 阶模态由 9.6 Hz 提 升至 25.61 Hz。结果表明，形貌优化技术能够有效提升动力电池上盖模态性能，为动力电池 上盖优化设计提供了参考。

Abstract: The modal of the power battery cover directly affects the noise, vibration, harshness (NVH) performance and structural durability of the whole vehicle. In order to improve the modal performance of the power battery cover, the cover structure is optimized by using topography optimization method. Based on solver MSC. Nastran analyzed the modal of the power battery cover. According to the analysis results, the first modal that is of great concern was optimized by using the topography optimization method. By changing the structural characteristics of the cover, the first modal of the cover is increased from 9.6 Hz to 25.61 Hz. The results show that the topography optimization technology can effectively improve the modal of the power battery cover, which provides a reference for the optimization design of the power battery cover.
