【摘要】：流体压力脉动致振是影响大型服务器液冷系统管道可靠性的重要因素之一。基于ANSYS workbench中的模块连接功能,提出一种液冷管道振动应力分析方法。首先在Static Structural模块中分析管道在稳定流体压力作用下的应力情况,然后在Harmonic Response模块中分析管道在流体压力脉动作用下的响应情况。测量实际管道的振动加速度,并结合有限元仿真计算结果进行对比分析,确定液冷管道中流体的压力脉动幅值。分析结果表明:弯管处是管道上应力最大的部位,应优先进行振动可靠性分析。该成果可为大型服务器液冷系统管道可靠性研究提供了一种可行的振动分析方法。
[Abstract]:Fluid pressure pulsation induced vibration is one of the important factors affecting the pipeline reliability of large scale server liquid-cooling system. Based on the module connection function in ANSYS workbench. A method of vibration stress analysis for liquid-cooled pipeline is proposed. Firstly, the stress of pipeline under steady fluid pressure is analyzed in Static Structural module. Then the response of the pipeline under the action of fluid pressure pulsation is analyzed in the Harmonic Response module, and the vibration acceleration of the actual pipeline is measured. The pressure pulsation amplitude of the fluid in the liquid-cooled pipeline is determined by comparing and analyzing the finite element simulation results. The results show that the bending pipe is the most stressed part of the pipeline. Vibration reliability analysis should be given priority, and this result can provide a feasible vibration analysis method for pipeline reliability research of large scale server liquid-cooled system.
