摘要

随着储能行业的迅猛发展，在运输过程中的安全性是储能系统结构评估的重点。为探明某储能电池柜的动力特性和随机振动下的受力机理，本工作展开扫频振动试验，得到储能电池柜

向的一阶频率为7.485 Hz，阻尼比为0.051，

向的一阶频率为8.431 Hz，阻尼比为0.070；同时，本工作采用国际安全运输协会(ISTA)3E路谱进行竖直方向(

向)随机振动试验，试验表明，柜体振动后基本完好。本工作基于有限元分析方法建立储能电池柜精细化仿真模型，进行模态分析、扫频振动和随机振动仿真分析。模态分析的仿真与试验结果误差在5%以内，验证了模型的有效性；扫频振动仿真提取的加速度响应与实测数据对比，以9号传感器为例，吻合度较高；随机振动仿真得到的应力云图与试验磨损位置吻合，验证了有限元模型的准确性。本工作的研究成果为电池柜的振动性能评估和结构优化提供了重要参考，验证后的有限元模型可有效预测电池柜的振动特性，为后续产品设计和结构优化提供可靠的技术支撑。

Abstract

As the energy storage industry rapidly expands

ensuring the safety of energy storage systems during transportation has become a critical aspect of structural safety evaluations. This study investigates the dynamic characteristics and mechanical response of a specific energy storage battery cabinet under random vibration. Sinusoidal sweep vibration tests determined the first-order frequencies and damping ratios: 7.485 Hz with a damping ratio of 0.051 in the

-direction

and 8.431 Hz with a damping ratio of 0.070 in the

-direction. Vertical (

-direction) random vibration tests

condu

cted using the ISTA(International Safe Transit Association) 3E road spectrum

showed that the battery cabinet remained largely intact. A refined finite element analysis (FEA) model was developed to simulate the cabinet

with modal

sinusoidal sweep

and random vibration analyses performed. The modal analysis simulation results deviated by less than 5% from experimental measurements

validating the model's accuracy. Comparisons of acceleration responses from the sinusoidal sweep simulations

exemplified by sensor #9

showed strong agreement with experimental data. Moreover

stress distribution maps from the random vibration simulations corresponded well with wear-prone areas observed experimentally

further confirming the FEA model's reliability. This research provides valuable guidance for evaluating the vibration performance and optimizing the structural design of battery cabinets

offering a robust technical foundation for future energy storage products.
