Abstract

The invention discloses an air-conditioner random vibration comprehensive test device and a method thereof. The air-conditioner random vibration comprehensive test device comprises a vibrostand body has a vibrostand countertop used for transmitting vibration to an air-conditioner to be tested, a vibration chamber for holding the air-conditioner to be tested, a refrigerant leakage detector for detecting whether a refrigerant of the air-conditioner positioned inside the vibration chamber leaks or not, and a stress-strain testing device for detecting the stress-strain condition of pipelines of the air-conditioner to be tested. According to the invention, exact time of brittle fracture or fatigue crack of the air-conditioner pipeline system under different working conditions and different incentive intensity conditions can be determined rapidly. With the combination of the stress-strain testing device arranged on the pipeline system, an S-N curve of fatigue life of a real product-level brittle fracture part of the air-conditioner pipeline system can be calculated accurately, and reliability and life of the air-conditioner product can be accurately designed according to the curve. In addition, the device provided by the invention is simple to operate and has high testing efficiency.

Description

[0001] technical field [0002] The invention relates to a vibration testing device and method, in particular to a random vibration comprehensive testing device and method of an air conditioner. Background technique [0003] In order to avoid damage to air conditioner products during transportation from the manufacturer to the customer's home, air conditioner companies usually conduct long-distance transportation experiments and random vibration experiments on air conditioner products in the early stages of product development. Although the effect of the long-distance transportation experiment is good, it is time-consuming and costly, which is often unaffordable for enterprises. Therefore, various packaging and transportation experiments that simulate transportation conditions, that is, random vibration experiments, have become widely used by major air conditioner manufacturers. [0004] The advantages of the existing air conditioner random vibration experiment are low cost...
