The invention discloses a novel light double-V sandwich structure chassis of a mine resistant ambush protected vehicle. The novel light double-V sandwich structure chassis of the mine resistant ambush protected vehicle comprises a vehicle body gradient porous metal foam horizontal sandwich bottom plate and double-V gradient porous metal foam sandwich structures, wherein the vehicle body gradient porous metal foam horizontal sandwich bottom plate is welded to the bottom of the mine resistant ambush protected vehicle body, and the double-V gradient porous metal foam sandwich structures are welded to the two sides of the bottom of the vehicle body gradient porous metal foam horizontal sandwich bottom plate. Guide grooves are formed in the blast face of each double-V gradient porous metal foam sandwich structure. Due to the shell configuration design of the double-V structures, upward brisance can be effectively dispersed to the side faces of the vehicle, initial peak loads generated when blast shock waves act on the double-V structures are reduced to the greatest extent, upward chassis deformation caused by blast shock is reduced, and impact force directly borne by staff is relieved. Through the guide grooves in the outer blast faces of the double-V sandwich structures, bomb fragments and blast shock waves are dispersed rapidly, the action time of blast shock waves is shortened, and impact on positions under the chassis is reduced.
