摘要
ASME Ⅷ-2的2013年版对防止热应力棘轮现象的规定相对于过去历版作了较多修改。从引起热应力棘轮现象的原理和原始依据、规定的制订根据以及相关标准(诸如EN 13445,ASME Ⅷ-3和原ASMEⅧ-2等)的同一内容出发,对此提出了一些商榷。
There are comparatively more changes in 2013 edition ASME Ⅷ-2 code on the protection of thermal stress ratchet.In this paper,based on the principle of thermal stress ratchet occurrence,the limit to this phenomena and relevant contents in other standards,such as EN 13445,ASME Ⅷ-3 and old ASME Ⅷ-2,some deliberations were presented.
