Design and Analysis of Vehicle Energy Absorption Structure with Hydraulic Pressure
Energy absorption structure is important in vehicle passive safe protection, which can absorb the energy as vehicle collision to protect the passenger safety, in this paper, a new type of vehicle energy absorption structure with hydraulic pressure for automotive of middle-mounted and rearmounted engine, and numerical simulation to optimize for structure of hydraulic energy absorption structure with dynamics mesh technology. The results show that the through-hole structure and opened press is optimized, when the diameter of through hole is 12-14ram, and the opening pressure of the check valve is 5000-6000Pa, the absorbing energy structure being made of the piston cylinder could have good effect.
