Device and method for simulating corrosion and fatigue coupling test on lifting rope under ozone atmosphere environment

Abstract

The invention discloses a device for simulating a corrosion and fatigue coupling test on a lifting rope under an ozone atmosphere environment. The device comprises a corrosion test box, wherein a detection control device is arranged on the corrosion text box; a telescopic fixed rod is arranged on the side surface of the corrosion test box and is fixed on the corrosion test box through a hoop; the telescopic fixed rod is fixedly connected with a vertical column of a fatigue testing machine; a sample rack is arranged in the corrosion test box; a lifting rope test section is arranged on the sample rack. The invention also provides a method for simulating the corrosion and fatigue coupling test on the lifting rope under the ozone atmosphere environment. The device and the method which are disclosed by the invention can be used for performing an ozone corrosion test on the lifting rope and performing a corrosion and fatigue test on the lifting rope under corrosion and load coupling action. The device and the method have the characteristics of real-time and visible test process, low cost, simple structure and convenience in operation.

Description

technical field [0001] The invention belongs to the interdisciplinary technical field of environmental corrosion and bridge structure experimental mechanics, and in particular relates to a device for sling corrosion fatigue coupling test simulating ozone atmospheric environment, and the invention also relates to a sling corrosion fatigue coupling simulating ozone atmospheric environment method of testing. Background technique [0002] In order to cross the great rivers and seas, more and more long-span suspension bridges have been built and are under construction. The safety of the sling is an important guarantee for the safe passage of the suspension bridge. It is generally believed that installing a shock absorber on the sling can ensure the safety of the sling. However, the suspension suspension technology exchange meeting of the Xihoumen Bridge, which was opened to traffic at the end of 2009, was held in Zhoushan on April 16, 2014. The damage of the cable shock absorbe...
