本文件规定了屈曲荷载的评估方法，其中: a） 考虑到液压缸的几何模型，这意味着它不会将液压缸视为等效柱，b）可用于表2中规定的所有类型的油缸安装和杆端连接，c）包括安全系数k，由执行计算的人员设置，并与计算结果一起报告，d） 考虑可能的离轴载荷，e）考虑液压缸的重量，这意味着它不会忽略施加在液压缸上的所有横向载荷，f）可以通过简单的计算机程序实现，g）认为液压缸完全伸展。 购买本文件时可获得的所有当前修订均包含在购买本文件中。

This document specifies a method for the evaluation of the buckling load which: a) takes into account a geometric model of the hydraulic cylinder, meaning it does not treat the hydraulic cylinder as an equivalent column,b) can be used for all types of cylinder mounting and rod end connection specified in Table 2,c) includes a factor of safety, k, to be set by the person performing the calculations and reported with the results of the calculations,d) takes into account possible off-axis loading,e) takes into account the weight of the hydraulic cylinder, meaning it does not neglect all transverse loads applied on the hydraulic cylinder,f) can be implemented as a simple computer program, andg) considers the cylinder fully extended.All current amendments available at time of purchase are included with the purchase of this document.
