To solve the problem that a separate device for measuring the center of gravity or the like is required in a conventional vehicle crash test apparatus.

The vehicle crash simulator system includes: a pitching table on which the body to be tested is mounted and which is swingable in a pitching direction; a load cell unit with a spring and a load cell unit which can be interposed between the body to be tested and the pitching table; a horizontal acceleration control/measurement device applying horizontal acceleration to the pitching table; a pitching control/measurement device swinging the pitching table in the pitching direction; and a simulation control device calculating the mass, the position of the center of gravity, and the pitching inertial moment and reproducing the crash motion of the vehicle. Accordingly, measurement of the mass, the position of the center of gravity, and the inertial moment of the body to be tested and the simulation of the vehicle crash test are achieved.
