目前工作的目的是开发一种方法来表征力传感器在正弦激励下使用的一级标准作为源的可追溯性。在这项工作中的影响因素进行了研究，并建立了一种方法，以尽量减少其贡献，以及在动态条件下进行的校正。这些结果将允许实现一个适当的表征力传感器正弦激励下，这将是必不可少的，其在动态条件下的进一步正确使用。传感器表征的可追溯性基于力的直接定义，即质量乘以加速度。为此，传感器加载有不同的校准负载，并通过振动器系统保持在不同的正弦加速度下，该振动器系统能够产生高达100 m/s2的加速度，频率从5 Hz到2400 Hz。加速度是通过激光测振仪测量的，可追溯到时间和长度单位。还需要多通道数据采集系统来同时真实的采集所涉及的仪器的电输出信号。
The aim in the current work is the development of a method to characterize force sensors under sinusoidal excitations using a primary standard as the source of traceability. During this work the influence factors have been studied and a method to minimise their contributions, as well as the corrections to be performed under dynamic conditions have been established. These results will allow the realization of an adequate characterization of force sensors under sinusoidal excitations, which will be essential for its further proper use under dynamic conditions. The traceability of the sensor characterization is based in the direct definition of force as mass multiplied by acceleration. To do so, the sensor is loaded with different calibrated loads and is maintained under different sinusoidal accelerations by means of a vibration shaker system that is able to generate accelerations up to 100 m/s2 with frequencies from 5 Hz up to 2400 Hz. The acceleration is measured by means of a laser vibrometer with traceability to the units of time and length. A multiple channel data acquisition system is also required to simultaneously acquire the electrical output signals of the involved instrument in real time.
