| Summary: | The working conditions of the hydraulic turbine are frequently changed.If the connecting bolts between the top cover and the stay ring are subjected to a load,and they are loose or broken,the serious consequences such as the plant flooding and even the machine destruction and death may occur.This paper establishes the calculation model of the connecting bolts between the top cover and the stay ring of hydraulic turbine by the ANSYS Workbench software,and calculates and analyzes the maximum stress of connecting bolts and the position of the dangerous section under different load rejection conditions by the finite element analysis method.The calculation results show that:when the load rejection is 82.5 MW,the stress on the connecting bolts is the largest.Therefore,the ultrasonic online monitoring and early warning system shall be applied to monitor the most dangerous bolts in real time to prevent accidents. |
