如图


1，        Flow induced vibration analysis has identified problems: Fluid Elastic Instability:  2 warnings, of which 2 serious; Resonance Assessments:  8 warnings, of which 0 serious.
2，        There is an unsupported straight tube span of 1461.24 mm which exceeds the TEMA maximum unsupported straight tube span of 1320.8 mm.
请问有没有厉害的马友知道这两个问题怎么解决啊？？

振动分析提示有流体弹性不稳定性，这个必须要消除。看出现在哪个部位，主要方法：1）降低流速；2）增加支撑
