| description | In order to reduce the pressure impact of continuous rotary electro-hydraulic servo motor, ensure the smooth pressure transition during the motor commutation, and improve the control accuracy, a kind of pre-compression chamber structure was proposed. The fluid domain models with pre-compressed chamber structure were established. The decompression process of the motor in long radius arc region and boosting process in short radius arc region were simulated and analyzed by FLUENT software. Through comparing and analyzing pressure distribution, outlet flow rate, and cross-section flow rate of fluid models, basing on a drosophila optimization algorithm, the optimum structure size of the pre-compression chamber of the motor is obtained. The results show that the optimal side length of the pre-compression chamber is 10 mm in the compression process, while the optimal side length is 26.273 mm in the decompression process. The pre-compression chamber structure can effectively reduce the pressure impact of the continuous rotary electro-hydraulic servo motor. |
