Complete-period vibration evaluation method during design of air conditioner pipeline system

Abstract

The invention relates to the technical field of air conditioners, and discloses a complete-period vibration evaluation method during design of an air conditioner pipeline system, and aims to improve the vibration reliability of an air conditioner compressor pipeline system, reduce the breakage risk of a pipeline and prolong the life of the pipeline. In the conceptual design stage of the air conditioner pipeline system, a vibration condition of a compressor pipeline can be evaluated through pipeline vibration simulation, so as to determine whether the pipeline can be machined or not according to an evaluation result; therefore, the design cost is reduced, and the trial manufacturing success rate of the pipeline is increased; then a stress experimental datum is used as a dynamic response parameter during simulative reverse calculation of a compressor load, so that the reliability of the stress experimental datum is guaranteed; the pipeline vibration simulation and a stress experiment are subjected to cooperative research, to improve the vibration reliability of the air conditioner compressor pipeline system.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a full-cycle vibration evaluation method for design of an air conditioner pipeline system. Background technique [0002] At present, the main role of applying CAE (Computer Aided Design) simulation technology in the conceptual design of air conditioner piping system is to choose the best solution, while there are few studies on the use of CAE simulation technology to evaluate the pipeline vibration status in the pipeline concept design stage. After the pipeline enters the prototype processing stage, it is necessary to do a stress test to evaluate the vibration level of the pipeline according to the test results. Although the accuracy of the stress test data is high, it is inevitable that there will still be misjudgments and missed judgments at the frequency points with high stress This phenomenon reduces the reliability of pipeline vibration, which puts forward higher re...

After the pipeline enters the prototype processing stage, it is necessary to do a stress test to evaluate the vibration level of the pipeline according to the test results. Although the accuracy of the stress test data is high, it is inevitable that there will still be misjudgments and missed judgments at the frequency points with high stress This phenomenon reduces the reliability of pipeline vibration, which puts forward higher requirements for the accuracy of stress test data. The traditional method of improving the accuracy of stress test data is mainly to increase the number of experiments and stress test points, which increases the Experimental cost and testing period
