摘要

本文提出了一种理论-实验方法，用于预测疲劳裂纹增长动力学，并确定氢气中结构责任元素的寿命。根据所创建的疲劳裂纹生长计算模型、实验构建的 35KhN3MFA 钢疲劳破坏动力学图，确定了在空气和气态氢环境中被表面半椭圆形裂纹削弱的涡轮发电机转子轴的残余寿命。与在空气中的残余寿命相比，在氢气中转子轴的残余寿命缩短了两个数量级。

Assessing of the Life Time of a Shaft with a Crack in Hydrogen

A theoretical-experimental approach for predicting the kinetics of fatigue crack growth and determining the life time of the responsible elements of structures in hydrogen is proposed. Based on the created calculation model of fatigue crack growth, experimentally constructed kinetic diagrams of fatigue failure of 35KhN3MFA steel, the residual life of the rotor shaft of the turbo generator, weakened by a surface semi-elliptical crack in air, and in gaseous hydrogen environment, are determined. Hydrogen reduces the residual life of the rotor shaft by two orders of magnitude in hydrogen, compared to its residual life in air.
