DETAILED DESCRIPTION

[0015] Refer to Figures 1-4As shown, the automobile seat foam block attenuation characteristic test device provided by the embodiment comprises a rectangular sliding frame 1, a wire displacement sensor 2, a guide block 3 with a vertical guide hole inside, a counterweight block 4, a pressurizing plate 5, an electromagnet 6, an electric chuck 7, a foam placing platform 8, a rectangular frame 9, and a servo controller. The rectangular sliding frame 1 is composed of two vertically arranged light shaft rails 10, an upper horizontal plate 11 and a lower horizontal plate 12. The rectangular sliding frame 1 is slidably connected in the vertical guide holes of the two guide blocks 3 through the two light shaft rails 10. The height-adjustable foam placing platform 8 is installed at the bottom position of the rectangular frame 1 and below the rectangular sliding frame 1. The detachable pressurizing plate 5 is installed on the lower horizontal plate 12. The wire encoder of the wire displacement sensor 2 is installed on the rectangular frame 9 close to the guide block 3. The wire end of the wire displacement sensor 2 is fixedly connected to the lower horizontal plate 12 of the rectangular sliding frame 1. The electromagnet 6 is fixedly connected to the rectangular frame 9 and located directly above the rectangular sliding frame 1. The electric chuck 7 is fixedly connected to the upper horizontal plate 11 of the rectangular sliding frame 1. The rectangular sliding frame 1 is magnetically attracted to the electromagnet 6 through the electric chuck 7. The counterweight block 4 is installed on the rectangular sliding frame 1. The foam placing platform 8 comprises a bearing plate 13 with air holes and four supporting legs 14 supporting the bearing plate 13. The bearing plate 13 is fixedly connected to the supporting legs 14 through bolts and nuts and is adjusted in height on the supporting legs 14.
