The invention relates to a device for determining the inertial parameters of a body, particularly a motor vehicle. Said device comprises a receiving platform (P) on which the body (F) can be placed. The receiving platform (P) is provided with a central, especially spherical joint (G) about which the receiving platform (P) can be moved with three degrees of freedom (x, y, z) by means of drive units (Z, Z, Z). The invention further relates to a method for determining the inertial parameters of a body, particularly by means of a device disclosed in one of the preceding claims. In said method, a control system is provided which allows a receiving platform (P) and a body (F) mounted thereon to be moved about a central pivot (G) with three degrees of freedom (x, y, z). The forces measured in the joints (G, G) and the angles measured in the central joint (G) are fed to an evaluation process, by means of which the inertial parameters of the body (F) are determined especially by using laws of mechanics, particularly the principle of angular momentum.
