Junker test. The more exciting Mar 3, 2017 · The Junker vibration test in accordance with DIN 65 151 is a proven method of testing the safety of threaded connections when exposed to vibrations and dynamic loads. The more exciting Introducing the Junker Test The most rigorous method for testing bolted joints is known as a Junker test. The Junker vibration test –named after Gerhard Junker, who published the breakthrough article “New Criteria for Self-Loosening of Fasteners Under Vibration” in1969[4]–hasbecomethestandardfordynamictestingof fasteners and analysis of their self-loosening behaviour. The results provide the design engineer with information about joint design safety and how effective their selected fasteners really are. 1 Recommendations concerning the test rig and which data to collect . During the Junker test, the The Junker test assesses the loosening characteristics of fasteners. The more exciting In this video we explain the principles behind the Junkers test and show a test being conducted which demonstrates the process of self-loosening of threaded The Junker vibration test described in DIN 65151 allows us to compare different fasteners and their ability to maintain clamp load under extreme conditions in just 30 seconds. Learn how to compare the relative performance of fastener locking solutions under transverse vibration according to ISO 16130, DIN 65151 and DIN 25201-4 standards. Find out the differences between the original DIN 65151 and the new DIN 25201 standards for Junker tests. 3.
