In order to explore the failure of high-strength bolts in engineering fields such as pressure vessels,aerospace,nuclear power,etc.,in the face of high pressure,low temperature,radiation and other harsh environments,analyze its impact on production and equipment life,and deeply explore the failure reasons,so as to put forward effective preventive measures.By summarizing the failure cases of high-strength bolts in practical use,the complex reasons of high-strength bolts failure are systematically analyzed,and possible preventive strategies are explored on this basis.The results show that there are many reasons for the failure of high-strength bolts,including material selection,design error,processing quality,installation operation and so on,and a series of specific preventive measures are put forward for many factors.Combined with the research results,it put forward a series of constructive suggestions on the design,processing and installation of high-strength bolts.The implementation of these preventive measures is expected to reduce the failure rate of high-strength bolts and improve the overall engineering safety,thus avoiding economic losses caused by failure and prolonging the operating life of mechanical equipment.
