Embodiment 1

[0061] Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0062] Examples, see attached figure 1 The flow chart of a design method for an induced anti-scour energy-absorbing support member is shown, including the following steps:

[0063] Step 1. Determine the design maximum and minimum values ​​of the length 1, width 3, height 2, and thickness 4 of the anti-scour energy-absorbing support components according to the structure of the roadway anti-scour hydraulic support, and use the mechanical drawing software AutoCAD to draw the anti-scour energy-absorbing support The 3D model of the member, where the dimensions of length 1 and width 3 are the same due to the port of the anti-scourrence support member being square, such as Figure 4 shown;

[0064] Step 2. According to the length, width and height of the anti-scour energy-absorbing support members, use the formula P for calculating the average bearing capacit...

Abstract

The invention discloses a design method for an induction type anti-impact energy absorption supporting construction member. The method comprises the following steps that: firstly, determining the sizeof the anti-impact energy absorption supporting construction member, and drawing a three-dimensional model; then, through a size value, calculating yield strength; thirdly, through the yield strength, obtaining a nominal stress-nominal strain curve; fourthly, calculating a true stress curve and a true strain curve; and finally, utilizing a finite element to calculate the bearing capacity of the anti-impact energy absorption supporting construction member. Through the above method, a design method capable of lowering the design cost of the anti-impact energy absorption supporting constructionmember while accuracy is guaranteed is put forward, and therefore, the technical problems of big errors and high cost in the prior art are solved.

Description

technical field [0001] The invention relates to the field of anti-scour support for rock burst in coal mines, in particular to a design method of an induced anti-scour energy-absorbing support component. Background technique [0002] With the increase of coal mine mining depth, the rock burst is more and more serious, resulting in the impact damage of the roadway surrounding rock, the support damage, and the collapse of the roadway, which seriously threatens the life safety of the coal mine workers. As a key component of the roadway anti-scour energy-absorbing hydraulic support, the induced anti-scour energy-absorbing support member can coordinate with other components on the support to absorb external impact energy instantly. At present, the rationality of the design is determined by the method of structure and size design, and the method of verifying its bearing capacity through the compression test of the laboratory test. However, the induced anti-shock energy-absorbing c...
