In order to verify the applicability of the computer numerical simulation method under complex engineering conditions, and solve the problem that it is difficult to guarantee the normal construction of underground projects with a depth of more than 1 km (it is difficult to carry out multiple field attempts under highdepth conditions, and if you simply use ordinary the calculation method, its calculation accuracy is difficult to guarantee). For the construction of complex geological conditions of an underground mine with a depth of 1300 m in the Central Plains of China, based on the finite difference method (FDM) with high calculation accuracy, using FLAC 3D software based on FDM, and using progressive design method (PDM) [1], design a variety of different schemes and analyze the mechanism of force and deformation of the surrounding rock mass of the project. Apply the obtained optimal scheme in actual engineering, and monitor the actual force and deformation. Comparing the results of the computer numerical simulation with the monitoring results, the results show that the computer numerical simulation method can also have good application in the actual engineering under the geological conditions of ultra-kilometer depth. It also provides theoretical basis and technical guidance for engineering hypothesis under approximate conditions.

This paper proposes an evolved quasi-3D analysis method (EQAM) that can extremely reduce analysis time by applying it to models where 3D analysis is essential. The conventional quasi-3D analysis is a method that can equalize a 3D analysis with multiple 2D analyses and is widely used for 3D models that take a long analysis time. However, the quasi-3D method still has the problem of taking a long time to interpret because it requires increasing the number of quasi segments to obtain accurate results. Therefore, this paper proposes a method of deriving a magnetic flux linkage, torque, voltage, torque-current phase angle curve (T-ꞵ curve) by interpreting only one step rather than all steps in multiple quasi segments. Compared to the 3D analysis, the EQAM reduced the T-ꞵ curve extraction time by 99.1% and reduced the capacity of the analysis file by 99.6%. In terms of analysis accuracy, the average torque error rate is 0.20% and the voltage error rate is 2.88% at the operating point. The validity of the proposed method was verified by confirming that the analysis time and file capacity reduction rate were significantly higher than the error rate. Therefore, EQAM is expected to be of great help to researchers facing time problems by being applied to various fields and studies that require 3D finite element analysis.INDEX TERMS electromagnetic analysis, finite element analysis, permanent magnet motors, Quasi-3D, yokeless and segmented armature

In this paper, an analysis of electromagnetic–mechanical characteristics according to the shaft materials of a permanent magnet synchronous motor was performed. In general, the shaft of an electric motor rotating at high speed uses various materials, considering the mechanical rigidity and electromagnetic characteristics. However, because the material of the shaft has a significant influence on the electromagnetic performance according to the characteristics of the non-magnetic and magnetic materials, electromagnetic characteristics analysis was performed according to the material of the shaft. In addition, because the machine rotating at a high speed entails mechanical problems owing to the centrifugal force, the mechanical stability was secured through critical speed characteristic analysis according to each material after performing the von Mises stress analysis of the permanent magnet and sleeve.
