车载动力蓄电池多自由度道路模拟试验的研究

Multi-axial road simulation of automotive storage cell

介绍了多自由度模拟试验台的系统组成,并精确地分析其在试验台上模拟汽车零部件在空间的六个自由度运动状态和再现汽车零部件的实际运行状况的理论依据,对轿车上的动力蓄电池进行室内道路模拟试验,通过实践进行了验证.其结果可用于汽车零部件的道路模拟试验,以缩短试验周期,节省试验费用,具有较好的应用和推广价值.

In this study, a framework of the multi-axial shaking table （MAST） is first introduced. Meanwhile, the six-axial motion states of the automobile parts are analyzed and represented based on the testing table. A laboratorial road simulation test is then conducted upon automotive storage cell to validate the proposed MAST. For the purpose of for time- and cost-saving, this approach can be extended and adapted to diverse fatigue and durability tests for various vehicles.
