Abstract

The invention discloses a fastener natural atmospheric environment test reliability evaluation method, and relates to the technical field of mechanical equipment reliability test. According to the invention, a representative fastener variety is selected, and the corrosion resistance of the fastener in a natural atmospheric environment is comprehensively assessed from multiple aspects. The method comprises the following steps: testing the basic performance of the fastener before putting; and testing the surface state and the performance change of the fastener after the fastener is put for different periods. By analyzing and evaluating the detection results, the corrosion type and the corrosion mechanism of the fastener are known and mastered, so that references are provided for reasonable selection, effective design, corrosion delaying and loss reduction caused by corrosion of the fastener on the structural member, and the requirement for corrosion evaluation of the fastener in the natural atmospheric environment is met.

Description

technical field [0001] The invention relates to the technical field of reliability testing of mechanical equipment, in particular to a method for evaluating the reliability of fasteners in natural atmospheric environment tests. Background technique [0002] Fasteners are also called standard parts in the market, which is a general term for a type of mechanical parts used when two or more parts (or components) are fastened and connected into a whole. Most of the fasteners are used in the atmospheric environment. Atmospheric corrosion is a more common phenomenon. Whether it is outdoors or indoors, the atmosphere will corrode the fasteners. Fasteners are the most widely used general-purpose parts on model products. Their performance and quality will directly affect the design level and quality level of products, and the reliability and corrosion resistance of fasteners. It plays a very important role in the safety of model products. [0003] According to the traditional faste...
