摘  要：
在锂离子电池驱动的农用车辆中,电池包的抗振性是直接影响整车可靠性的原因之一。但在农用车辆行业,对电池包的振动特性研究较少,由商用车直接移植的标准电池包因机械振动方面原因引发的故障较多,严重影响整车的可靠性,且存在一定的安全隐患。利用有限元分析法建立电池包计算模型,对其进行模态分析和在振动条件下的动态响应分析,并通过台架振动试验以及跑车试验进行强度验证。分析结果表明,该分析方案能有效识别电池包低阶模态敏感部位,优化后的电池包在实验室振动条件以及实车试验下能保证强度可靠。该研究能为类似产品的研发设计提供有效的理论依据。

摘  要：
In a lithium-ion battery-driven agricultural vehicle,the vibration resistance of battery pack is one of reasons that directly affect reliability of vehicle. However,in agricultural vehicle industry,there are few researches on vibration characteristics of battery pack. The standard battery pack directly transplanted by commercial vehicles has many faults caused by mechanical vibration,which seriously affects reliability of vehicle and has certain safety hazards. Battery pack calculation model was established by finite element analysis method,and its modal analysis and dynamic response analysis under vibration conditions were carried out. The strength verification was carried out by bench vibration test and sports car test. The analysis results showed that the analysis scheme could effectively identify low-order modal sensitive parts of battery pack,and optimized battery pack could ensure strength and reliability under laboratory vibration conditions and actual vehicle test. This research could provide an effective theoretical basis for R&D design of similar products.
