摘　　要：作为满足振动试验必不可少的工具,好的振动试验系统可以保证试验件在不失真的情况下试验,使试验受控,然而,如果振动台台面加速度均匀度不好,就会导致发生过试验或欠试验等问题。以某型振动台为例,研究加速度均匀度的测试方法,通过试验分析加速度均匀度的分布规律,可以提高振动试验的精度。As an indispensable tool for vibration test, good vibration test system not only can ensure the smooth process of a vibration test without distortion, but also can make the vibration test under control. However, if the acceleration uniformity of a shaker is not well, the problem of over or under test will occur. Taking a vibrating table as an example, the test method of acceleration uniformity is studied; the distribution of the acceleration uniformity is shown by analyzing the experimental result, which can improve the accuracy of the vibration test.
