| 摘 要： | 为研究某款防滑差速器内部流场分布规律,在流固耦合理论指导下,采用软件仿真的方式对该款差速器内部流场规律进行了研究。首先根据防滑差速器内部结构建立其三维流体域的简化模型,并利用Xflow软件对不同转速、不同油液浸没深度对其内部油液速度稳态波动时间的影响进行了仿真;其次以内部流场先达到稳态平衡为优化目标,以流体域润滑油体积和达到速度稳态平衡所需时间为评价指标,对防滑差速器内部流场分布最优时的浸油深度进行预测,结果显示润滑油浸油深度在-0.03 m时,差速器内部流场分布最优。

| Abstract: | In order to study the internal flow field distribution of an anti slip differential, under the guidance of fluid structure coupling theory, the internal flow field of the differential was studied by software simulation. Firstly, a simplified model of three-dimensional fluid domain is established according to the internal structure of the anti slip differential, and the influence of different rotational speed and different oil immersion depth on the steady-state fluctuation time of internal oil velocity is simulated by using Xflow software. Secondly, with the internal flow field reaching the steady-state equilibrium first as the optimization goal, and the fluid domain lubricating oil volume and the time required to reach the steady-state equilibrium velocity as the evaluation index, the immersion oil depth at the optimal distribution of internal flow field was predicted. The results showed that when the lubricating oil immersion depth was -0. 03 m, the flow field distribution inside the differential was optimal. |
