电动式振动台加速度幅值测量结果不确定度分析

Electrodynamic Vibration Table Acceleration Amplitude Measurement Uncertainty Analysis

电动式振动试验台通常用来检验产品能否经受住长时间振动而不至改变其性能或不至于导致某些机械损坏,所以,振动试验台自身的各种参数是否准确可靠,对正确地评价产品质量有着非常直接的影响,根据国家检定规程JJG190-1997电动式振动台试验台的要求,对使用中电动振动台测量结果进行不确定度评定,使其测量结果更加合理可靠。

Electrodynamic vibration table is used to test the product can withstand long vibration and not change the performance or not lead to some mechanical damage, so the parameters of the vibration table is accurate and reliable, to correctly evaluate has a direct impact on product quality, according to the verification regulation JJG190-1997 the requirements of the electrodynamic vibration platform test bench, the use of electric vibration in a uncertainty evaluation of measurement results, the measurement result is more reasonable and reliable.
