Digital simulation model correcting method and system

The invention discloses a digital simulation model correcting method and a digital simulation model correcting system. The digital simulation model correcting method comprises the following steps: after a general modeling tool and a professional modeling tool acquire a simplified digital simulation model and an exquisite digital simulation model of a simulated object respectively, firstly, performing preliminary verification and model structure and parameter correction on the simplified digital simulation model by using exquisite digital simulation model; secondly, performing verification and model parameter correction on the corrected simplified digital simulation model by using a first group of experimental data of the simulated object till the obtained simplified digital simulation model meets requirements on measurement indexes for model verification under the group of experimental data; thirdly, performing verification and model parameter correction on the simplified digital simulation model meeting the first group of experimental data by using a second group of experimental data of the simulated object till the obtained simplified digital simulation model meets requirements on measurement indexes for model verification under the two groups of experimental data, and thus finally determining the simplified digital simulation model.
