“…At present, there are some problems in the quality evaluation and audience scoring standard of computer composition in piano sound simulation [6], especially in the data utilization of vocal music simulation for different simulation methods [7]. Luo et al found that most computer vocal music simulation technologies still adopt the single simulation idea of sound, while ignoring the impact of indicators such as sound color, melody and audience satisfaction effect on the simulation [8].…”

The application and economic efficiency evaluation mode of traditional composition in the field of modern music cannot meet the needs of various types of music in China, especially Guqin music. Based on this, this paper studies the big data simulation model of Guqin sound synthesis and plucking based on computer composition technology. The computer composition technology uses the discrete dynamic modeling technology of complex system to complete the computer simulation of Guqin sound through the analysis of the correlation between Guqin music data and realizes the storage and analysis of the generated Guqin sound data. In addition, the technology can analyze the data information of composition mode in the piano sound plucking simulation model with the classical Guqin music data stored in the cloud system over the years and then feed it back to relevant professionals for verification. The experimental results show that the Guqin sound simulation model can efficiently compare and analyze the melody and other data of classical Guqin sound with the simulated Guqin sound and can realize secondary data mining. This paper studies the application of computer composition method based on discrete dynamic modeling technology in Guqin sound simulation, which has certain reference significance for improving the cloud data in China’s modern music field and the intelligent construction of Guqin sound data cloud storage system.

“…6A, pp. 4059-4066 teristics will change fundamentally, and the insulating ability will be lost seriously [7]. The temperature rise limit of the winding is basically determined by the maximum allowable temperature of the insulating material of the insulating structure and the temperature of the cooling medium [8,9].…”

Due to the insulation aging, demagnetization and other problems of the permanent magnet and insulating material in the permanent magnet synchronous hub motor under high temperature, the numerical simulation of the heat dissipation of surface mounted permanent magnet synchronous hub motor is proposed. According to the heat transfer of hub motor, the effect degree of heat conduction, heat convection and heat radiation is obtained, the heat transfer coefficient of each part is calculated, and the influence of motor insulation material on temperature rise is analyzed. The experimental results show that the heat dissipation of hub motor under natural cooling condition is poor, and the internal oil cooling method can effectively improve the heat dissipation of hub motor and reduce the temperature difference. When operating at high speed, this reduces the potential safety hazard.

“…Drive motor and battery are important components of regenerative braking, and their characteristics also affect the distribution of regenerative braking force. When the speed of the passenger car is low, and the motor speed doesn't reach the minimum speed of the power generation state, regenerative braking is not performed [22,23]. When the motor speed is less than the base speed, the motor works in the constant torque zone, and when it is higher than the base speed, the motor works in the constant power zone.…”

This research aims to reduce the impact of the regenerative braking force generated by the new energy vehicle on the braking performance during regenerative braking. It mainly focuses on the braking design scheme of pedal decoupling and the corresponding pedal decoupling strategy. First, the pedal decoupling scheme is designed, and the electronic mechanical assisted braking model and the overall model of the driving vehicle are established. The model includes electromechanical booster model, active accumulator model, and hydraulic braking model. The electromechanical booster model mainly includes the permanent magnet synchronous motor model and the transmission mechanism model. Then, the pedal decoupling strategy based on the new decoupling scheme is studied, and the decoupling process is divided into three stages. According to the control requirements of each stage, the control of pressure reducing valve and the pump motor in the electronic stability program (ESP) is realized, so as to adjust the brake circuit hydraulic pressure during the decoupling process. Moreover, the decoupling current is calculated to adjust the torque of the electromechanical booster motor, so as to adjust the pedal feel. Finally, the control strategy of the electro-mechanical assist motor is designed to realize the control of the motor. The experimental results show that the designed decoupling strategy can make the master cylinder hydraulic pressure change according to the distribution result of the braking force distribution strategy under the three braking strengths of low, medium, and high, which has a good decoupling effect. In addition, the decoupling electro-hydraulic compound braking realizes the precise control of the wheel cylinder pressure and effectively recovers the braking energy. The braking energy feedback efficiency reaches 54.8%. The designed decoupling strategy provides some references for the adoption of pedal decoupling in automobile assisted braking.
