This test simulates the vibration load of the component during vehicle operation. It is used to ensure the resistance of the component to electrical and mechanical fault patterns. This test includes a test bench test with mechanical stress on new parts. For this purpose, the battery is applied by means of a shaker test bench with a noise profile in the main excitation direction ( -axis vertically). In condensed form, this noise profile is intended to show the real use of the battery over a distance of max. of battery life. 该测试模拟车辆运行过程中零部件的振动负载。它用于确保零部件对电气和机械故障模式的抵抗力。该测试包括对新零件施加机械应力的试验台测试。为此,通过振动试验台施加电池,主要激励方向( 轴垂直)上的噪声轮廓。简而言之,这种噪声轮廓旨在展示电池在最大 电池寿命距离内的真实使用情况。
A resonant sweep is also performed before and after the noise profile in order to characterize the natural frequencies and to detect any changes in the natural frequencies caused by the noise profile. 在噪声轮廓之前和之后还进行了共振扫描,以表征自然频率并检测噪声轮廓引起的自然频率变化。

Sweep analysis & documentation 扫描分析和文档记录
The natural frequencies are determined by comparing the excitation signal with the resonator signal. To do this first determine the peaks of the resonator signal. If an acceleration of at least alim is reached in a peak of the response signal, i.e. if the excitation signal is amplified by , the corresponding frequency is evaluated as resonance inducing. For each individual sensor, the quotient of response and excitation is formed at each natural frequency to document the resonance strength via the positions. 自然频率是通过将激励信号与谐振器信号进行比较来确定的。首先确定谐振器信号的峰值。如果响应信号的峰值至少达到 alim 的加速度,即如果激励信号被放大 ,则相应频率被评估为诱导共振。对于每个单独的传感器,在每个自然频率处形成响应和激励 的商,以通过位置记录共振强度。
