Research on the Stability Problem of Hydroelectric Station Penstock under External Pressure

The process of losing stability and breach for reinforcing ring steel penstock under external pressure is very complex and a lot of factors work on this process, so the research about this problem is very difficult. At present, various calculating methods of this problem have their limitations, sometimes even the results have great differences. In this paper, the problem is simulated by artificial neural network and simulated annealing. Test results show that the method is feasible and its validity is verified. This paper provides an efficient solving path for stability problem of reinforcing ring steel Penstock under external pressure.
