Abstract

The invention relates to a test platform and a test method for an electromagnetic acceleration counterweight impact compression buffer tube, belongs to the technical field of impact compression tests,and solves the problems of large installation space, small speed range, poor initial speed controllability in front of an impact buffer tube, poor attitude stability in the impact process and low test efficiency of the existing drop hammer testing machine and drop hammer testing tower. The test platform comprises a control system, a mounting base, an electromagnetic ejection system, a counterweight impact system, a support guide device and a buffer tube mounting platform; the control system is used for controlling the test platform; the mounting base is horizontally arranged, and the electromagnetic ejection system is arranged on the mounting base and used for accelerating or decelerating the counterweight impact system in the horizontal direction; and the buffer tube mounting platform isarranged in front of the ejection direction of the electromagnetic ejection system. According to the invention, the required installation space is smaller, the environmental adaptability is better, the safety of personnel is prevented from being damaged by accidental falling of the drop hammer in the test process through the horizontal test, and the test safety is improved.

Description

technical field [0001] The invention relates to the technical field of impact compression tests, in particular to a test platform and a test method for electromagnetic acceleration counterweight impact compression buffer tubes. Background technique [0002] The buffer tube is a thin-walled part made of metal. The cross section is mostly circular or rectangular. When subjected to an impact load, the buffer tube produces plastic deformation through its own material to absorb the impact energy. It has the advantages of compact structure and high buffer efficiency. Therefore, it is often used as an energy-absorbing device for braking high-speed moving objects, such as automobiles, trains, and missile launchers. [0003] After the design of the buffer tube is completed, a large number of impact compression tests are required to verify its performance and reliability. At present, the most commonly used test method is the gravity drop weight test, including the use of drop weight ...
