标准范围

ISO 16063-31:2009规定了用于横向振动灵敏度测试的仪器和方法的细节。它适用于直线速度和加速度传感器。ISO 16063-31:2009中规定的方法和程序允许确定传感器对垂直于其几何灵敏度轴的平面内振动的灵敏度。因为这种横向灵敏度的大小可以随着所施加的振动的方向而变化，所以各种方法确定最大值。使用该值，可以计算换能器的横向灵敏度与几何轴上的灵敏度的比率。此外，可以确定出现最大横向灵敏度的角度。指定的方法和技术可以在不重新应用的情况下应用-在测试期间远离其安装表面安装换能器，从而避免在需要重复安装的方法中经常遇到的显著不确定性。规定的不同方法使用单轴激振器、双轴激振器或三轴激振器。三轴振动激励允许同时确定横向灵敏度和几何轴上的灵敏度，从而模拟换能器暴露于多轴振动的应用条件。ISO 16063-31:2009适用于1Hz至5kHz的频率范围以及1m/s2至1000m/s2（频率相关）和1mm/s至1m/s（频率相关）的动态范围。虽然在所有指定的系统中，可以实现这些范围，但通常每个系统都有限制，允许其在小得多的范围内使用。所指定的方法是通过与参考换能器和激光干涉仪进行比较。如果扩展不确定度表示为测试换能器在其敏感轴上的灵敏度的百分比，则规定的方法允许实现0.1%或更小的横向灵敏度（覆盖因子k=2）的扩展不确定度。

ISO 16063-31:2009 specifies details of the instrumentation and methods to be used for transverse vibration sensitivity testing. It applies to rectilinear velocity and acceleration transducers.The methods and procedures specified in ISO 16063-31:2009 allow the determination of the sensitivity of a transducer to vibration in the plane perpendicular to its geometric axis of sensitivity. Because the magnitude of this transverse sensitivity can vary with the direction of the applied vibration, the various methods determine the maximum value. Using that value, the ratio of the transverse sensitivity to the sensitivity on the geometric axis of the transducer can be calculated. In addition, the angle at which the maximum transverse sensitivity occurs can be determined.The methods and techniques specified can be applied without re-mounting the transducer away from its mounting surface during the test, thus avoiding significant uncertainties often encountered in methods which require repeated mounting. The different methods specified use a single-axis vibration exciter, a two-axis vibration exciter or a tri-axial vibration exciter. Tri-axial vibration excitation allows the transverse sensitivity and the sensitivity on the geometric axis to be determined simultaneously, thus simulating application conditions where the transducer is exposed to multi-axial vibration.ISO 16063-31:2009 is applicable to a frequency range from 1 Hz to 5 kHz and for a dynamic range from 1 m/s² to 1 000 m/s² (frequency dependent) and from 1 mm/s to 1 m/s (frequency dependent). Although among all the systems specified it is possible to achieve these ranges, generally each has limitations permitting its use in much smaller ranges.The methods specified are by comparison both to a reference transducer and to a laser interferometer.The methods specified allow an expanded uncertainty of the transverse sensitivity (coverage factor k = 2) of 0,1 % or less to be achieved, if the expanded uncertainty is expressed as a percentage of the sensitivity of the test transducer in its sensitive axis.
