标准摘要
[中文适用范围]： 本文件定义了为铁路牵引车和拖车车辆的乘客和机组人员设计的座椅实验室测试的规范。 它涉及频率范围 0.5 Hz 至 50 Hz 内的三轴直线振动。 它指定了座椅测试时使用的输入测试振动。 该文献使得能够以频率响应函数的形式表征振动传递至乘坐者的方式。 它还提供了一个估计器，显示座椅在乘坐者感知的动态舒适度方面的行为。 可以使用不同类型的激励，并且根据对座椅所遇到的振动环境的了解和振动模拟器的能力来描述不同类型的激励。 [外文原描述]： This document defines specifications covering laboratory tests for seats designed for passengers and crew in railway tractive and trailer vehicles. It concerns tri-axial rectilinear vibration within the frequency range 0,5 Hz to 50 Hz. It specifies the input test vibration to be used at seat testing. This document makes it possible to characterize, in the form of frequency response functions, the manner in which vibration is transmitted to the seat occupant. It also provides an estimator showing the behaviour of the seat in terms of dynamic comfort perceived by the seated person. Different types of excitations can be used and are described depending on knowledge of the vibration environment encountered by the seat and the capability of the vibration simulator.
