Abstract

The invention relates to a test platform and a test method for an electromagnetic acceleration counterweight impact compression buffer tube, which belongs to the technical field of impact compression test and solves the problems of large installation space, small speed range and impact buffering of existing drop weight test machines and drop weight test towers. Poor initial velocity control in front of the tube, poor attitude stability during impact, and low test efficiency. The test platform of the present invention includes a control system, an installation base, an electromagnetic ejection system, a counterweight impact system, a support guide and a buffer tube installation platform; the control system is used for the control of the test platform; the installation base is horizontally arranged, and the electromagnetic ejection system is designed On the installation base, it is used to accelerate or decelerate the counterweight impact system in the horizontal direction; the buffer tube installation platform is arranged in front of the ejection direction of the electromagnetic ejection system. The invention requires less installation space and better environmental adaptability, and the test in the horizontal direction avoids the accidental fall of the falling weight during the test process and endangers the safety of personnel, thereby improving the test safety.

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 ...
