For the record of equalizations of motion inertial and constrained frames are used. Transition matrices and kinematics relations are set between the different frames of reference. As the generalized coordinates of cushion (spring up) body three linear moving of centre of gravity and three corner of turn in relation to the constrained coordinate axes is used. Position of noncushion ( spring down) the masses described the vertical moving. Indignant motion is caused by the irregularity (unevenness) of road. Nonlinear resilient and dissipative forces in a saspension and tires are determined depending on their deformations. The design of casual indignations is conducted on the set spectral closeness. Motion of car on rough roads is accompanied the continuous vibrations of his construction.
