标准摘要
[中文适用范围]: ISO 7626 的这一部分规定了测量线性机械移动性和结构(例如建筑物、机器和车辆)的其他频率响应功能的程序,在测量期间使用连接到被测结构的单点平移振动激励器。 它适用于移动性、加速度或动态顺应性的测量,无论是作为驱动点测量还是作为传递测量。 它还适用于确定这些比率的算术倒数,例如自由有效质量。 尽管激励是在单个点处施加的,但是对于可以同时测量运动响应的点的数量没有限制。 例如,模态分析需要多重响应测量。 [外文原描述]: ISO 7626-2:2015 specifies procedures for measuring linear mechanical mobility and other frequency-response functions of structures, such as buildings, machines and vehicles, using a single-point translational vibration exciter attached to the structure under test for the duration of the measurement. It is applicable to measurements of mobility, accelerance, or dynamic compliance, either as a driving-point measurement or as a transfer measurement. It also applies to the determination of the arithmetic reciprocals of those ratios, such as free effective mass. Although excitation is applied at a single point, there is no limit on the number of points at which simultaneous measurements of the motion response may be made. Multiple-response measurements are required, for example, for modal analyses.
