本文件规定了安装振动传感器的不同方法的重要技术特性，并介绍了推荐做法。它还展示了加速计安装如何影响频率响应的示例，并给出了其他影响如何影响被观察结构中实际运动表示的保真度的示例。本文件适用于目前广泛使用的接触式加速度计。它适用于单轴和多轴传感器。本文件也适用于速度传感器。本文件使用户能够估计安装的局限性以及由此产生的潜在测量偏差。传感器安装问题不是影响加速度测量有效性的唯一问题。其他此类问题包括:横向移动、传感器对准、底座弯曲、电缆移动、温度变化、电场和磁场、电缆抖动和安装扭矩。安装以外的问题及其可能的影响不在本文件范围内。

This document specifies the important technical properties of the different methods for mounting vibration transducers and describes recommended practices. It also shows examples of how accelerometer mounting can influence frequency response and gives examples of how other influences can affect the fidelity of the representation of actual motion in the structure being observed.This document applies to the contacting type of accelerometer which is currently in wide use. It is applicable to both uniaxial and multi-axial transducers. This document can also be applied to velocity transducers.This document enables the user to estimate the limitations of a mounting and consequent potential measurement deviations.Transducer mounting issues are not the only problem that can affect the validity of acceleration measurement. Other such problems include, amongst others: transverse movements, alignment of the transducer, base bending, cable movement, temperature changes, electric and magnetic fields, cable whip and mounting torque. Issues other than mounting and their possible effects are outside the scope of this document.
