The article focuses on the basic NVH characteristics of a vehicle such as global static
stiffness, eigenfrequencies and local dynamic stiffness. We built the Smart Digital Twin of
serial SUV that allow reduce the time and costs of the design stage by reducing the number of
real tests. The optimal target values of static stiffness for the Frame and BIW were selected to
achieve the target static stiffness of the Trimmed body.
Keywords: finite element, frame, frequency, stiffness, vehicle.
