| 英文摘要: |
| The aim of the study is to investigate the impact of the buffer groove structure on the pressure of continuous rotation electro-hydraulic servo motor. The mathematical model of the motor valve plate with triangular groove and U-groove structure is established firstly, and the structure size of the two buffer grooves with better pressure drop effect is obtained by Matlab. Secondly, an established pressure gradient model is developed for the sealed canisters for electric motors using a combined groove structure. The bird swarm optimization algorithm is used to obtain the optimal dimensions for the combined depth and angle of the pressure groove. The flow field in the motor seal chamber is simulated and calculated by Fluent. This study compared the pressure field distributions in the motor’s sealing chamber using triangular and combined groove structures. It investigated the combined groove’s effect on the pressure impact during the commutation of a continuously rotating electro-hydraulic servo motor. It is found that the combined groove structure has a positive impact on reducing the pressure impact. The results indicate that the combined groove structure significantly enhances the efficiency of mitigating pressure shocks when the motor switches between high- and low-pressure chambers. |
