“…There are two main forms of division of building space: splitting vertically and splitting horizontally [18]. The splitting in the horizontal direction is relatively simple, and more independent space can be obtained only by adding a partition wall and satisfy the requirement to increase the amount of space used.…”

In order to solve the poor matching ability between concrete structures of traditional architectural space optimization design methods, it leads to the problem of low space optimization ratio, so based on virtual reality technology, the author proposes a new method for optimizing the space of concrete structure buildings. Using virtual reality technology to improve the basic structure of building space, reorganize the form through the design space, and optimize the design of the concrete structure building space function; based on the test model of virtual reality technology, design the matching method of concrete structure, increase the proportion of building space optimization, and adopt linear buckling method, geometric nonlinear method, and double nonlinear analysis method; the ultimate bearing capacity of steel structures of residential buildings in earthquake areas is tested. Experimental results show that for the simple structure building space, the average optimization ratios are 97.17% and 96.71%, respectively; for the complex structure building space, under the proposed optimization design, the average optimization ratio is maintained at 94.34%, and the error between the stress prediction value of the finite element model and the axial stress obtained by testing is less than 6%. Compared with the traditional space optimization design, in the proposed space optimization design method, the proportion of building space optimization is higher; it can be seen that the virtual reality technology has a better matching effect on the concrete structure, and the accuracy of the ultimate bearing capacity value obtained by prediction is high.

“…The vibration characteristics of the motor with different slot number and pole number combinations are analyzed by FEM, and the optimal combination mode is obtained according to the results. In order to reduce the vibration noise of PMSM, starting from the motor structure, the magnetic field of the motor can be optimized by changing the slot structure of the motor rotor, so as to improve the electromagnetic vibration force of the stator teeth and reduce the electromagnetic vibration noise of the motor [15]. In summary, many scholars have started their research on vibration and noise of motor mainly from the input of the inverter and the body structure [16]- [19].…”

In order to study the influence of harmonics on the vibration and noise of permanent magnet synchronous motor, this paper introduces an analysis method based on field-circuit coupling, and establishes a complete analysis process from the control strategy to the vibration and noise response of the motor. Firstly, the coupling model including control strategy, main circuit model and electromagnetic field model is established. Secondly, the finite element model of the permanent magnet synchronous motor under the influence of coupling is established to analyze and compare the electromagnetic force wave characteristics of the coupling excitation and the sinusoidal excitation. Then, the coupled electromagnetic force is loaded into the structural field to simulate and calculate the vibration and noise. Finally, the effectiveness of the model is verified through experimental sound pressure level comparison under steady-state and speed-up conditions, and it provides a reference for vibration and noise prediction of the motor system.

The adaptive backstepping control method of permanent magnet motor has the problems of complicated coordinate transformation process and high position tracking error. Based on this, an adaptive backstepping control method of permanent magnet synchronous motor based on RBF is proposed. According to the principle of electrical machinery, the electromagnetic wave and magnetic field data are obtained, and the mathematical model of permanent magnet synchronous motor is constructed. Under the condition of keeping the resultant magnetomotive force after coordinate transformation unchanged, the structure of motor torque neural network is established by RBF method, and the coordinate transformation process is optimized. Through the compensation control strategy, the adaptive backstepping control mode is designed to realize the adaptive backstepping control of permanent magnet synchronous motor. The simulation results show that the position tracking error of the proposed method is 4.549 mm when the running time is 7 s and 43.699 mm when the running time is 14 s, which proves that the adaptive backstepping control effect of the proposed method is better.
