Abstract: The geometric modeling and finite element modeling of the overall structure of electrostatic precipitator and its main components (top beam, column, bottom beam and support) are completed. The strength calculation is completed. The results show that the overall structure and main components of the electrostatic precipitator are designed reasonably, the structure is in a balanced state, the working condition is safe and reliable, the stress changes evenly and the stress distribution law. The maximum von Mises stress of the whole structure is 20.14   MPa. The safety factor is large, resulting in material waste. The optimization mathematical model is established. The dimensional parameters of the main frame structure of electric vehicle are calculated by using the first-order finite element analysis method of ANSYSrostatic precipitator were optimized. After optimization, more reasonable structural design parameters were obtained. The model weight is 72,344.11 kg, the optimal weight is 49,239.35 kg, and the revised weight is 53,645.68 kg. Compared with the model weight, the optimal weight decreased by 23,104.76 kg and the objective function decreased by 31.94 , while the revised weight decreased by 18,698.43 kg and the objective function decreased by 25.84 .
