标准摘要
[中文适用范围]： ISO 8686 的这一部分规定了计算载荷的通用方法以及用于选择载荷组合的原则，以根据 ISO 20332 证明 ISO 4306-1 中定义的起重机结构和机械部件的能力。 它基于刚体动力学分析和弹性静力学分析，但明确允许使用更先进的方法（计算或测试）来评估载荷和载荷组合的影响以及动态载荷系数的值，其中可以证明这些提供至少同等水平的能力。 ISO 8686 的这一部分规定了两种不同的应用： a) 为特定类型的起重机制定的更具体标准的一般形式、内容和参数值范围； b) 对于不存在特定标准的起重机类型，设计者或制造商与起重机购买者之间就载荷和载荷组合达成一致的框架。 [外文原描述]： ISO 8686-1:2012 establishes general methods for the calculating loads and principles to be used in the selection of load combinations for proofs of competence in accordance with ISO 20332 for the structural and mechanical components of cranes as defined in ISO 4306-1. It is based on rigid-body kinetic analysis and elastostatic analysis but expressly permits the use of more advanced methods (calculations or tests) to evaluate the effects of loads and load combinations, and the values of dynamic load factors, where it can be demonstrated that these provide at least equivalent levels of competence. ISO 8686-1:2012 provides for two distinct kinds of application: the general form, content and ranges of parameter values for more specific standards to be developed for individual crane types; a framework for agreement on loads and load combinations between a designer or manufacturer and a crane purchaser for those types of cranes where specific standards do not exist.
