Abstract

The invention relates to the technical field of air conditioners, and discloses a method, device and equipment for vibration operation analysis of an air conditioner outdoor unit. The method comprises the following steps: under the condition that a hammer made of two or more materials hammers at a set position of the outdoor unit of the air conditioner according to a set transmission path, according to a hammering force signal and a synchronously acquired target point sound signal, obtaining each structural acoustic transfer function corresponding to the materials; according to the correlation of each structural acoustic transfer function, determining the structural acoustic transfer function of the set frequency band as a to-be-spliced transfer function; and performing frequency band splicing on each to-be-spliced transfer function to obtain a structural path transfer function of the set transfer path, and performing vibration noise analysis of the air conditioner outdoor unit according to the structural path transfer function. Therefore, the accuracy of the transfer function is improved, and the vibration noise analysis accuracy of the air conditioner outdoor unit is further improved.

Description

technical field [0001] The present application relates to the technical field of air conditioning, for example, to a method, device and equipment for analyzing vibration and noise of an outdoor unit of an air conditioner. Background technique [0002] The noise and vibration phenomena of the outdoor unit of the air conditioner are often superimposed by multiple excitations arriving at the target position through different transmission paths. At present, in the process of air conditioner research and development, in order to further optimize the performance of the air conditioner, it is often necessary to comprehensively consider the conditions of various excitations and transmission paths, and the vibration and noise problem of the outdoor unit of the air conditioner can be simplified as "Source-Path-Acceptor" (Source-Path-Acceptor). Receiver) model to represent, calculate the response of each noise source or vibration source to the receptor through each path, and add these ...
