In order to solve the problem that the new hydraulic gate is difficult to manufacture experiment and debug in the real environment, the historical gate operation data was analyzed and transmitted based on the digital twin simulation platform. The designed gate was analyzed through numerical simulation, and the overall stress and deformation changes of the gate with different sub-gate opening degrees under hydrostatic pressure were analyzed. At the same time, the overall vibration frequency changes of the gate under the action of air and fluid-structure interaction were analyzed. The flow state of the fluid domain at the sub-gates with different opening degrees was simulated. The results show that with the increase of the opening of the sub-gate, the stress value of the gate varies from 58 MPa to 67.5 MPa, and the deformation change is not obvious; Compared with the natural vibration frequency of the gate in the air, the fluid-structure coupling effect will appropriate reduce the natural vibration frequency of the gate; Different sub-gate openings will affect the flow state of the fluid domain, and increasing the opening will reduce the water velocity. The results provide some references for its actual operation, maintenance and optimization of gate performance.

为解决新型液压闸门在现实环境下难以制造、试验、调试等问题,基于数字孪生仿真平台对历史闸门运行数据进行分析并传递,通过数值模拟仿真分析设计闸门在静水压力下不同子闸门开度的闸门整体应力、变形变化,同时分析在空气中及流固耦合作用下闸门整体振动频率变化,并模拟了不同开度子闸门处的流体域流动状态。结果表明,随着子闸门开度的增加,闸门所受应力值在58~67.5 MPa之间变化,所受变形变化不明显;与空气中的闸门自振频率相比,流固耦合作用会适当降低闸门的自振频率;不同子闸门开度会影响流体域的流动状态,且开度增加会降低水体流速。研究结果为其在实际运行、维护及优化闸门性能提供一定的参考。

为解决新型液压闸门在现实环境下难以制造、试验、调试等问题,基于数字孪生仿真平台对历史闸门运行数据进行分析并传递,通过数值模拟仿真分析设计闸门在静水压力下不同子闸门开度的闸门整体应力、变形变化,同时分析在空气中及流固耦合作用下闸门整体振动频率变化,并模拟了不同开度子闸门处的流体域流动状态。结果表明,随着子闸门开度的增加,闸门所受应力值在58~67.5 MPa之间变化,所受变形变化不明显;与空气中的闸门自振频率相比,流固耦合作用会适当降低闸门的自振频率;不同子闸门开度会影响流体域的流动状态,且开度增加会降低水体流速。研究结果为其在实际运行、维护及优化闸门性能提供一定的参考。

In order to solve the problem that the new hydraulic gate is difficult to manufacture experiment and debug in the real environment, the historical gate operation data was analyzed and transmitted based on the digital twin simulation platform. The designed gate was analyzed through numerical simulation, and the overall stress and deformation changes of the gate with different sub-gate opening degrees under hydrostatic pressure were analyzed. At the same time, the overall vibration frequency changes of the gate under the action of air and fluid-structure interaction were analyzed. The flow state of the fluid domain at the sub-gates with different opening degrees was simulated. The results show that with the increase of the opening of the sub-gate, the stress value of the gate varies from 58 MPa to 67.5 MPa, and the deformation change is not obvious; Compared with the natural vibration frequency of the gate in the air, the fluid-structure coupling effect will appropriate reduce the natural vibration frequency of the gate; Different sub-gate openings will affect the flow state of the fluid domain, and increasing the opening will reduce the water velocity. The results provide some references for its actual operation, maintenance and optimization of gate performance.
