本SAE标准定义了一种测量非公路自行式工作机器的坐着操作员在执行实际或模拟操作时所受全身振动的方法。它适用于通过座椅传递给操作员的振动。没有同等的ISO标准。在本文件正文中，定义了测量和记录非公路自行式工作机器的坐着操作员全身振动的条件。仪器规范、分析方法以及现场和操作条件说明允许以可接受的精度进行测量和报告。该程序包括在ISO2631规定的不同频率下对振动水平进行称重的方法。建议使用标准格式报告光谱数据。定义、仪器和分析方法也适用于实验室进行的操作员振动模拟试验。 本程序仅为测量方法，不适用于座椅系统的评估或选择。被ISO 2631取代。

This SAE Standard defines a method for the measurement of the whole body vibration to which the seated operator of off-highway self-propelled work machines is exposed while performing an actual or simulated operation. It applies to vibration transmitted to the operator through the seat. There are not equivalent ISO Standards.In the main body of this document, conditions are defined for measuring and recording whole body vibration of the seated operator of off-highway self-propelled work machines. The specification of instruments, analytic methods, and description of site and operating conditions allows the measurements to be made and reported with an acceptable precision. The procedure includes means of weighing the vibration level at different frequencies as specified in ISO2631. A standard format for reporting spectral data is recommended.The definitions, instruments, and analytic methods also apply to simulated tests for operator vibration as performed in laboratories.This procedure is a measuring method only and is not intended for the evaluation or selection of seating systems.Superseded by ISO 2631.
