Problems solved by technology
[0002] Air conditioning systems are often subject to extreme operating conditions and external damage during operation, resulting in accelerated aging of structural parts, failure of fixtures, and changes in fixed frequency or expected stiffness of pipelines
At this time, the air-conditioning pipeline system is very likely to cause resonance or forced vibration, resulting in increased pipeline stress, greatly reducing the long-term operating life of the pipeline, and abnormal leakage of the pipeline often occurs at the use end, and the reliability of the system operation is affected at the same time. Vital components become fragile

The invention discloses a pipeline structure, a method for optimizing pipeline vibration and a pipeline control system. The pipeline structure includes at least one adjustable section, the structure and / or orientation state of the adjustable section can be changed, and the adjustable section can be adjusted in the circumferential direction and the orientation state by changing the structure and / or orientation state of the adjustable section. / or mass distribution in the axial direction. The pipeline structure provided by the present invention includes an adjustable section whose structure and / or orientation state can be changed, so that when the stress of the pipeline exceeds a predetermined value, the structure and / or orientation state of the adjustable section is changed to make the pipeline fixed frequency And the fixed pretightening force changes, greatly reducing the vibration transmission excitation, making the pipeline stress smaller, prolonging the service life of the pipeline, and improving the reliability of the system using the pipeline.
Description
technical field [0001] The invention relates to the field of pipeline vibration, in particular to a pipeline structure, a method for optimizing pipeline vibration and a pipeline control system. Background technique [0002] Air-conditioning systems are often subject to extreme operating conditions and external damage during operation, resulting in accelerated aging of structural parts, failure of fixtures, and changes in fixed frequency or expected stiffness of pipelines. At this time, the air-conditioning pipeline system is very likely to cause resonance or forced vibration, resulting in increased pipeline stress, greatly reducing the long-term operating life of the pipeline, and abnormal leakage of the pipeline often occurs at the use end, and the reliability of the system operation is affected at the same time. Vital components become fragile. Contents of the invention [0003] In view of this, one of the objectives of the present invention is to provide a pipeline str...
