标准摘要
[中文适用范围]： 本国际标准提供了计算钢制拉杆机械强度的简化程序，无论是否有焊缝，适用于联合国欧洲经济委员会《车辆构造综合决议》(RE3) 中规定的 O1 和 O2 类中轴拖车。 因此，它仅适用于能够进行弯曲计算的简单结构。 [外文原描述]： ISO 7641:2012 gives a simplified procedure for the calculation of the mechanical strength of steel drawbars, whether there are welds or not, for centre-axle trailers Categories O1 and O2 as specified in the UNECE, Consolidated Resolution on the Construction of Vehicles (R.E.3). Consequently, it only applies to simple constructions that enable a calculation in bending.
英文名称Road vehicles — Trailers up to 3,5 t — Calculation of the mechanical strength of steel drawbars
