摘要
机械冲击是新能源动力电池研发过程中安全性、可靠性考核试验的重要测试内容。本文深入研究机械冲击试验的测试原理,通过建立机械冲击动力学模型,探讨波形发生器、试验高度、动力电池样品质量和阻尼器粘阻系数对动力电池机械冲击测试结果的影响。在此基础上,提出一种高效调节目标参数从而快速获得理想测试结果的试验方法,缩短了实际工程测试的调试时间并提高测试效率提供了良好的理论基础。
Mechanical shock is an important part of safety and reliability test in the development of new energy battery. In this paper,the testing principle of mechanical shock is deeply studied, and the dynamic model of mechanical shock is established, the effects of waveform generator, test height, test sample quality and damper viscosity coefficient on the mechanical shock results of power battery were investigated. On the basis of this, a method of adjusting target parameters efficiently to obtain ideal test results is proposed, which provides a good theoretical basis for reducing debugging time and improving test efficiency in practical engineering test.
