机动车零部件检测实验室振动试验的内部质量控制方法

摘要

According to the characteristics of vibration test, a Z-shaped sample of aluminum material is used as the quality control sample in the automotive vehicle component testing laboratory. Using the sweep-frequency technique within a certain frequency range, the frequency value corresponding to the maximum point of the scanning curve is obtained, and considered as the vibration test result, thereby the vibration test result is quantiifed. By using this method to carry out the internal quality control of vibration test in the laboratory, the expected effect could be achieved.%根据振动试验的特点，采用铝材料制作的Z形样件作为质量控制活动中的质控样品。在一定频率范围内对工件的特定点进行扫频，取其扫频曲线中的最大点对应的频率作为振动试验的结果值，从而将振动试验结果量化。采用此方式进行机动车零部件检测实验室振动试验的内部质量控制，可以达到预期的效果。
