The invention discloses a high-speed projectile body model evaluation method based on a multi-layer structure target plate of a penetration ship, and relates to the technical field of high-speed projectile body penetration. The method comprises the following steps: building a high-speed projectile body model; establishing a ship multilayer structure target plate standard model; determining material parameters of the high-speed projectile body model and the target plate standard model; setting a plurality of projectile landing point positions on the first layer of target plate when a high-speed projectile body penetrates through the multi-layer structure target plate; for each missile landing point position, determining the flight distance and the deflection angle of the high-speed missile body penetrating through each layer of target plate; according to the flight distance and the deflection angle, determining a trajectory change value of the high-speed projectile body penetrating through each layer of target
