Abstract

The invention relates to a structural non-linear fatigue damage testing system, belonging to the field of manufacturing of test equipment. The system consists of a dynamic balance wheel bracket, a dynamic part bracket, a T-shaped lead screw, a static part bracket, a stay-wire-type photoelectric encoder, synchronous pulleys, a servo motor, a distance regulation wheel mechanism, a load sensor, a variable-frequency speed regulating motor and other parts. The structural non-linear fatigue damage testing system has the advantages that the structure is novel, is loaded in a horizontal manner, is applicable to testing of test pieces with different sizes, has a wide range of regulation and facilitates the installation of the test pieces; and the load average of rope samples is controlled in real time through the servo motor, so that the stability and reliability of tests are guaranteed, and the testing times, load variation and displacement variation are recorded in real time for testing the load-bearing limit and service life limit of the rope samples. Dynamic parts can be connected by a relative special fixture to perform simulation tests on a shock absorber, thereby detecting the service life of the shock absorber.

Description

technical field [0001] The invention belongs to the field of test equipment manufacturing, and is mainly used for fatigue life testing and creep performance testing for nonlinear fatigue damage of non-metallic materials and metal materials. Background technique [0002] Now structural parts are more and more widely used in production, and rope parts, whether metal or non-metal composite materials, are used in various production fields. It can measure and monitor the entire stretch and fatigue process of rope parts. Clamp and test test pieces such as ropes by changing different types of fixtures, and judge the life of rope parts through the analysis of experimental data; and perform simulation tests of shock absorbers by changing the connection mode of the fixtures. [0003] Especially when the offshore operation needs to stabilize the hull and when the ship is docked, ropes are required to be fixed. Due to the corrosiveness of seawater, especially the corrosion of rope part...
