Structure Design (FEA)

Finite element analysis (FEA) method simulate the real physical system (geometry and load conditions) by means of mathematical approximation.

To solve problem, it subdivides a large problem into smaller, simpler parts that are called finite elements. The simple equations that model these finite elements are then assembled into a larger system of equations that models the entire problem.

FEA could help increase accuracy, enhance design and better insight into critical design parameters, virtual prototyping. FEA method is applied for the runner design of some special power stations, especially the high head Pelton power station, according to the simulation analysis of force and displacement of the runner under various working conditions, we find the weak links and strengh it accordingly, so runner's strength ect overall performance could be better guaranteed, service life extended. Through the finite element analysis, bucket broken and crack phenomenon which caused by strength problems could be effectively prevented, thus ensure the unit safety.
