Embodiment 1

[0029] The energy-absorbing support equipment provided in this embodiment is a frame structure, see figure 1 , preferably, the frame structure may be a rectangular frame structure, of course, in other embodiments, it may also be other frame structures. Each frame of the frame structure is composed of several metal columns, elastic energy-absorbing units and pressure sensors. Among them, the elastic energy-absorbing unit is installed between two adjacent sections of metal columns, and is used to measure the energy absorbed by the supporting equipment. The pressure sensor is installed between two adjacent metal columns and is used to measure the pressure on the supporting equipment. Specifically, it can be as figure 1 As shown, the left side is composed of a metal post, an elastic energy-absorbing unit 11-1n, and a pressure measurement sensor 10; the right side is composed of a metal post, an elastic energy-absorbing unit 31-3p, and a pressure measurement sensor 10; the upper ...

Embodiment 2

[0050] On the basis of Embodiment 1, this embodiment provides a parallel energy-absorbing support equipment, which includes: a measuring circuit and several energy-absorbing support equipment provided in Embodiment 1. Taking the parallel energy-absorbing support equipment composed of two energy-absorbing support equipment as an example, the energy absorption calculation of parallel energy-absorbing support equipment is as follows:

[0051] Left deformation size:

[0052] Right deformation size:

[0053] Upper deformation size:

[0054] Downside deformation size:

[0055] Left energy absorption size: E 1 =F 11 L 11 +F 12 L 12 +…+F 1i L 1i +…+F 1n L 1n

[0056] Since the force on the left elastic energy-absorbing unit is equal, that is: F 11 =F 12 =…=F 1i =…=F 1n =F 1

[0057] Therefore, the magnitude of energy absorption on the left side is:

[0058] In the same way, the energy absorption on the right side is: E 3 =F 3 L 3

[0059] The energy ab...
