Embodiment Construction
[0034] Below in conjunction with accompanying drawing and specific example the present invention will be further described:
[0035] Such as figure 1 As shown, the embodiment of the present invention uses a steam turbine as an example for illustration, specifically including the following steps:
[0036] S1. Select the simulation temperature field sampling point set of the steam turbine;
[0037] Firstly, the temperature state data of the rotor in the steam turbine is collected from the beginning of acceleration to the stable speed, and then the collected data is simplified and losslessly compressed and encoded.
[0038] S11. For the finite element analysis results of K (K>48) simulated temperature fields, calculate x for every two points on the temperature field i and x j The semivariance between:
[0039]
[0040] Among them, y (k) (x i ) is the midpoint x of the kth result i the temperature value above;
[0041] S12. Randomly select M sampling points on the simul...
