Vibration Test

振动测试

A cell is charged at standard method,then installed onto the vibration desk with clamps. Equipment parameters of frequency and amplitude are as follows(the frequency is to be varied at the rate of 1oct/min between 10 and 55 herts,and repeat vibration for 30min.The cell is to be tested in three mutually perpendicular

directions):    frequency:10Hz~30Hz

amplitude: 0.38mm     frequency:30Hz~55Hz

amplitude: 0.19mm

电芯按6.2或6.3的规定充电结束后，将电芯用夹具安装在振动台的台面上，按下面的振动频率和对应的振幅调整好实验设备，X，Y，Z三个方向每个方向上从10～55Hz循环扫频振动30min，扫频速率为1oct/min；

振动频率：10Hz～30Hz 位移幅值(单振幅)：0.38mm；

振动频率：30Hz～55Hz 位移幅值(单振幅)：0.19mm。
