Abstract

The extrusion deformation of metal tube is an important form of high efficient cushioning braking.At present, the response characteristics of different structural forms under dynamic impact conditions is still lack of systematic understanding.Based on the thick-walled metal tube, the numerical study was carried out on the response of the compression deformation buffering braking.Firstly, with reference to the test state and results, the finite element analysis and calculation model of the thick-walled metal tube buffer braking device was established, and the quasi-static simulation analysis was carried out and checked, and then on this basis, the finite element method and display dynamics algorithm were used to study and analyze the cushioning braking response characteristics of thick-walled metal tube and the main factors affecting the buffer force.The results show that: ① the thick-walled metal tube buffer braking structure has the characteristics of small size, stable impact load and strong deformation capacity; ② the dynamic response of the thick-walled metal tube buffer braking device can be clearly characterized by this calculation model; ③the main structural factors affecting the buffer force are the lower inner hole diameter, the upper inner hole diameter and the external diameter of the buffer tube.The ratio of the inner diameter of the buffer tube to that of the upper part D 1 should be controlled between 0.7 and 0.8, and the ratio D 2 should be controlled between 1.8 and 2.0.When the ratio is smaller, the impact rod will recoil.When the ratio is larger, the impact rod will be subjected to greater impact force.The braking of the inertia braking section of the buffer cylinder also has a large fluctuation influence.According to the different buffer braking requirements in different engineering applications, the effective braking load can be obtained by setting reasonable parameters of the inner and outer diameter of the buffer tube.It can provide reference for related research and engineering application.
