Abstract
The invention belongs to the field of strength tests, and particularly relates to bending rigidity test equipment. The equipment comprises: a test bench, a first arresting cable, a second arresting cable and a flitch. A baffle is arranged on the test bench and divides the test bench into a first area and a second area; one end of the first arresting cable is arranged in a groove of the first area and is fixed with the test bench through a hoop, the other end of the first arresting cable is suspended outside the test bench and is provided with a first joint, and the first joint is provided with a weight; a second joint is arranged at one end of the second arresting cable, the second joint bypasses a steering wheel and then is hinged to a fixing rod in the second area, the other end of the second arresting cable is suspended outside the test bench and provided with a third joint, and a weight is arranged on the third joint; a first flitch is used for calibrating the first arresting cable, and the second flitch is used for calibrating the second arresting cable. The test result is easy to extract and operate and convenient to replace, loading of different loads is achieved, and the bending rigidity of the arresting cables of different thicknesses can be tested.
Description
technical field [0001] The application belongs to the field of strength testing, and in particular relates to a bending stiffness test testing equipment. Background technique [0002] The arresting cable exhibits highly nonlinear mechanical behavior during the impact of tire rolling and hook cable engagement. Under high-speed impact, there are both tensile waves propagating along the axial direction of the arresting cable and bending waves propagating along the direction of the aircraft. The characteristics have a great influence on the success of the shackle engagement and the arresting hook load. The nonlinear bending stiffness of the arresting cable directly affects the dynamic characteristics of the arresting cable. In order to accurately simulate and analyze the characteristics of the arresting cable, it is necessary to test the bending stiffness through experiments. [0003] At present, the arresting cable test only has the axial tensile stiffness and breaking force t...
