Bolt loosening test device for simulating corrosion environment and test method thereof

Abstract

The invention discloses a bolt loosening test device for simulating a corrosion environment and a test method thereof. The bolt loosening test device comprises a test machine body, a workbench is installed in the testing machine body, and an insulating ferrule is fixedly installed in the workbench through bolts. A shoe-shaped gold ingot platform is arranged in the insulating ferrule; a lower clamp is installed on the shoe-shaped gold ingot table, an upper platform is installed above the workbench, a chuck used for fixing the upper clamp is fixedly installed on the lower surface of the upper platform, and a micro-motion motor and a guide rail motor are fixedly installed on the upper surface of the upper platform. A plate sample is installed between the upper clamp and the lower clamp, a pre-tightening force sensor is installed on the plate sample, and a bolt sample penetrates through the pre-tightening force sensor and is installed on the plate sample and the lower clamp. According to the invention, a bolt loosening failure experiment can be effectively carried out on a bolt sample in an environment which is very close to a real working condition, the bolt loosening failure behavior of the bolt in a complex environment such as seawater can be accurately measured, and the authenticity of experimental data is improved.

Description

technical field [0001] The invention belongs to the technical field of bolt loosening test, and in particular relates to a bolt loosening test device and a test method for simulating corrosion environment. Background technique [0002] Due to the advantages of simple structure, high reliability, and easy assembly, bolted connection is one of the most widely used connection methods in mechanical systems. In practical applications, under the influence of vibration, shock and other factors, bolt fasteners often suffer failure problems mainly caused by bolt connection looseness. The existing bolt loosening test device is mainly aimed at the bolt loosening test research in the atmospheric environment, and cannot conduct experiments on the bolts in the complex liquid environment and the electrochemical corrosion environment. Contents of the invention [0003] The object of the present invention is to address the above-mentioned deficiencies in the prior art, and provide a bolt ...
