ISO 2631的这一部分为将ISO 2631-1应用于评估机械振动对固定导轨系统中乘客和机组人员舒适性的影响。它旨在用于由购买、指定或使用固定导轨系统的组织提供，以帮助他们了解导轨的设计以及系统的其他特征与舒适性之间的关系乘客和机组人员。这些指南建立了系统间相对舒适度的评价方法，而不是绝对的舒适程度。ISO 2631的这一部分适用于暴露于沿x-、y-和z轴，以及围绕这些（以身体为中心）轴的旋转振动。其目的是就舒适度评估作为沿着和围绕产生身体运动的车辆轴线的运动的函数。这个ISO 2631的一部分不适用于可能造成创伤的高振幅单瞬变，例如由车辆事故或“纵向松弛作用”产生的“磨合”造成的，也不适用于高振幅可能影响健康的振动。就ISO 2631本部分而言，固定导轨乘客系统包括轨道系统（重型和轻型轨道）、磁悬浮（磁悬浮）系统和橡胶轮胎地铁型系统，以及任何系统上面列出的类型具有倾斜功能，可在穿过弯道时补偿横向加速度。ISO 2631的这一部分提供了关于极低频加速度（0.1 Hz至0.5 Hz）影响的指南经历了可能导致运动病的垂直力。这些力可能是由曲线的组合引起的过渡、超高和倾斜车身技术。然而，ISO 2631的这一部分并不是为了给出指导横向或纵向极低频加速度（低于0.5 Hz）的舒适性影响部队。这种加速度可以由导轨几何形状（水平对齐和倾斜）产生。ISO 2631的这一部分为仅基于运动环境的平顺性评估提供了指导。

This part of ISO 2631 provides guidance on the application of ISO 2631-1 to the evaluation of the effects ofmechanical vibration on the comfort of passengers and crew in fixed-guideway systems. It is intended to be usedby organizations which purchase, specify or use fixed-guideway systems, to help them to understand therelationship between the design of the guideway as well as other features of the system and the comfort ofpassengers and crew. These guidelines establish methods for the evaluation of relative comfort between systems,as opposed to absolute levels of comfort.This part of ISO 2631 is applicable to people in normal health exposed to rectilinear vibration along their x-, y- andz-axes, as well as rotational vibration about these (body-centred) axes. It is intended to provide guidance on theassessment of comfort as a function of motions along and about vehicle axes that produce the body motions. Thispart of ISO 2631 is not applicable to high-amplitude single transients which may cause trauma, such as thoseresulting from vehicle accidents or "run-ins" produced by "longitudinal slack action", nor is it applicable to highamplitudevibration which may affect health.For the purposes of this part of ISO 2631, fixed-guideway passenger systems include rail systems (heavy and lightrail), magnetically levitated (MAGLEV) systems and rubber tyre metro-type systems, as well as any of the systemtypes listed above that incorporate a tilt capability to compensate for lateral acceleration when traversing curves.This part of ISO 2631 provides guidance on the effects of very low-frequency accelerations (0,1 Hz to 0,5 Hz)experienced as vertical forces that may cause kinetosis. These forces may be caused by combinations of curvetransition, super-elevation and tilt-body technology. However, this part of ISO 2631 is not intended to give guidanceon comfort implications of very low-frequency accelerations (below 0,5 Hz) experienced as lateral or longitudinalforces. Such accelerations can be generated by guideway geometry (horizontal alignment and cant).This part of ISO 2631 gives guidance on the evaluation of ride comfort based on motion environment only.
