约束条件对往复式压缩机管系结构固有频率的影响

Effect of Constraints on Natural Frequency of Reciprocating Compressor Piping Structure

依据浓缩质量法和变分法建立压缩机管道的振动向量方程,运用有限元分析的方法对往复式压缩机出口管系的结构固有频率进行模拟计算,并分别讨论不同的约束条件对往复式压缩机管系结构固有频率的影响。

Based on the concentrated quality and the variational method, the vibration vector equation for compressor pipeline was found, and finite-element analysis was applied to simulate the exit-piping structure＇ s natural frequency of reciprocating compressor, including the discussion of constraints＇ effect on the piping structure＇ s free frequency.
