| Abstract: | In the joint-axis bolt stretch process of the turning wheel of the Three Gorges Right Bank Hydropower Station,the bolt is incapable of stretching to the manufacturer's design value.Calculation and analysis show that the bolt stretch value can be reduced without influencing the safe operation.The joint-axis bolt-stretch value and its safety factor are analyzed,and the result can be used as reference in the installation project. |
