摘要：
To handle the complex situation of uncertain parameters of the drive motor of the electric vehicle，an analysis method for the vibration characteristics of the drive motor considering mixed parameter uncertainty is proposed. Firstly，the response models of the radial electromagnetic force，torque ripple and cogging torque of the drive motor are established based on the neural network surrogate model. Then，the uncertain parameters of drive motor are described by the mixed uncertainty model，where the uncertain parameters with sufficient information are described as random variables，while the uncertain parameters with limited information are described as interval variables. Next，the Taylor series expansion-central difference method（ TSE-CDM）is derived to calculate the mixed uncertain responses of the vibration characteristics of drive motor through combining Taylor series expansion and central difference method．Finally，a Monte Carlo method is given as the reference method to verify the effectiveness of TSE-CDM. The numerical analysis results of a drive motor show that the vibration characteristics of the drive motor can be calculated efficiently and accurately based on the 2D finite element model and the neural network model；and the mixed uncertain responses of the vibration characteristics of the drive motor can be effectively solved by TSE-CDM. © 2023 SAE-China.
