GB/T 11349.2-2006 in English

《GB/T 11349.2-2006振动与冲击 机械导纳的试验确定 第2部分：用激振器作单点平动激励测量》由TC53（全国机械振动、冲击与状态监测标准化技术委员会）归口，主管部门为国家标准化管理委员会。
本部分规定了用连接式激振器单点平动激励测量结构（如建筑物、机器和车辆）的机械导纳或其他频率响应函数的方法。 本部分适用于导纳、加速度导纳或位移导纳的测量，既可以是驱动点测量，也可以是传递测量。它还适用于确定这些比值的倒数，如自由有效质量。尽管采用单点激振，但可同时测量的运动响应的测点数目没有限值，例如，模态分析中要求的多点响应测量。

Scope

This standard specifies methods for measuring the mechanical admittance or other frequency response functions of structures such as buildings, machines and vehicles using a single-point translational excitation of a connected vibrator. This standard applies to the measurement of admittance, acceleration admittance or displacement admittance, either driving point measurement or transfer measurement. It is also suitable for determining the inverse of these ratios, such as free effective mass. Although single-point excitation is used, there is no limit to the number of measurement points that can simultaneously measure the motion response, for example: multi-point response measurement required in modal analysis.
