在用HTRI设计真空冷滚器时出现振动警告信息,请问怎么办?
在用HTRI设计真空冷滚器时出现如下警告信息:NOTE-In acoustic vibration calculations, at least one frequency ratio for the first mode is greater than 1.2. For region in which this condition occurs, the program calculates a maximum Chen number of 2206.02. Consider checking for higher mode acoustic vibration.请问怎么办?
{:1110_553:} 真空状态下气体流速高,声学振动分析中频率比容易出现超标。
降低管间的气体流速即可,比如增大折流板间距、增大管间距、增大壳体直径等。
