Description

Technical Field

[0001] The utility model relates to the technical field of gas spring production, in particular to a horizontal fatigue testing machine for gas spring production. Background Art

[0002] Fatigue testing of gas springs after production is a very important step for the following reasons: to ensure product quality, gas springs often need to withstand multiple expansion and contraction actions in actual use. For example, in the support of a car trunk, the gas spring will expand and contract once each time the trunk is opened and closed. Through fatigue testing, this frequent use scenario can be simulated to test whether the gas spring can maintain good performance during long-term use, thereby ensuring that the product quality meets the standards. Many industries have strict quality requirements for gas springs, such as the medical device field. For example, the gas spring support part of a medical bed, if it fails due to fatigue during use, may cause safety hazards to patients. Fatigue testing can detect potential quality problems in advance and ensure the reliability of the gas spring in actual application.
