摘要
本文通过使用状态下对螺栓轴力实测一年的数据,分析20MnTiB扭剪型高强度螺栓紧固轴力变化规律,论证其轴力满足原设计安全度。
Based on the data got from the tests on the axial force of bolt under the state of application during
one year the auther analyzes the changing laws of the axial force of 20MnTiB torque-shear type of
high-strength bolt, and confirms the axial force meets the requirement of the safety in the original design.
