摘要(Abstract):

空调管路中的排气管和回气管在长期工作下因振动而产生疲劳和松动,这将会影响管路的使用性能。针对空调管路振动问题,建立了管路模型,运用ANSYS中的workbench模块对管路进行模态分析和谐响应分析,并对比分析了阻尼和管路结构对系统固有频率的影响,通过改变固有频率来避开管路共振。
The exhaust pipe and return pipe will produce fatigue and loose under the long-term vibration.It will influence the use of performance of pipes.In order to study the vibration of pipeline.The pipeline model was established based on workbench software,and the modal analysis and harmonic response analysis were carried out.Compared the natural frequency of damping and pipeline structure,by changing the natural frequency to avoid resonance.

关键词(KeyWords): 管路振动;模态分析;谐响应分析;workbench
