振动试验中多点控制方法的分析与应用

摘要

As an effective means of simulation reliability in the real environment, vibration test has been widely used in the performance test of mine electrical products. In this paper, the sinusoidal vibration test is introduced, and then through several tests from usually work, it is illustrated that the multi control points method in vibration test can be used to ensure the accuracy of the test, compared with a single point of control, it can avoid overtesting or undertesting situation.%振动试验作为检验产品可靠性及模拟产品真实使用环境的一种有效手段，已被广泛应用于矿用电气产品的性能考核试验中。首先简单介绍了正弦扫频振动试验，然后就工作中遇到的几个试验，说明在振动试验中，多点式传感器控制方法相对于单点控制，可以较好地保证试验的准确性，从而避免"过试验"或"欠试验"情况的发生。
