Protection type vehicle bottom blast environment simulation device

The invention discloses a protection type vehicle bottom blast environment simulation device. The protection type vehicle bottom blast environment simulation device comprises a protection wall, a fixed platform fixedly connected with a lower portion of the protection wall, and a supporting adjusting mechanism arranged at a lower portion of the fixed platform, wherein the protection wall comprises an inner wall, a middle wall and an outer wall which are sequentially and concentrically arranged from inside to outside, the inner wall and the middle wall are big-end-up conic cylinders, the outer wall is a cylindrical cylinder, multiple closely-arranged horn holes are arranged on the inner wall and the middle wall, each horn hole is a big-end-inside hole, a central axis points to a blast center, an inner side of the middle wall is pasted with foamed aluminum, and an inner side of the outer wall is pasted with foamed aluminum. According to the simulation device, a small-scale test can be carried out by a tester, and the high-precision test data can be acquired while the blast environment is guaranteed to be safe.
